damn thats a lotta stuff! i've been wondering some easy stuff to do to get a little bit more power out of my 5.3 in my tahoe, mostly just a shade more low end torque. Sounds like headers is the most reasonable option... yes?

also this list only goes up to 2002.. 2003 should be the same right?

do y'all recommend anything else sub $700 for low end torque for my 5.3? Thanks fellas! :worship:

Can I recommend something for tuning your PCM? Do a search for HPTuners, it allows you to modify all of your pcm values to how ever you choose. Plus it has a scanner that logs all of your pcm values and it can even deleted trouble codes. Very worthwhile program if you want to tune your 99+ V8 truck for more power. :D

What about some headers? There's so many, what would fit a 00' 4.8? And still be legal.

What is the best way to spend $1500 on a 5.3L? I'm interested in exhaust, Air-Flo, and some sort of computer programmer, and any thing else I can get my hands on within my budget. Any suggestions would be greatly appreciated.

12-24-2004, 09:46 PM
Well I've done most of this stuff. The thing that made the biggest difference was the cam. I'm running a Lunati 55002. Most of you have automatics so you will need to use a higher stall torque converter to compensate for the slight loss of low end power. Also raising the rev limiter will probably be required to get the most out the extended power band. You can use the stock valvesprings with this model so the cam and supplies will run you around $400. If you tow or do not wish to change the converter I would look for a different cam. There are plenty available from Competition, Crane, Crower and some more I can't think of right now. Anyway a lot of bang for the buck but a lot more work.

I've installed a hypertech power programmer III, flowmaster 30 series cat-back duals and a K&N fipk, on my 03 sierra, total cost was about $1600 cdn. (1200-1300 u.s.).The results were pretty impressive although I doubt the performance gain claimed by the manufacturers is that high. The stock h.p. was 295 after the mods the claimed h.p. gains should have bumped me up to 350-360 ponies. The exhaust sounds awesome and the programmer, air-box mods improved responsiveness, especially at mid rpms. Not bad gains for the money. Smoked two hemis, bring on the fords!!

I had a Jet chip on my 5.3. Had many problems...truck would not shift and also had problems with the gauges not reading correctly after installation of the chip. I know it was not a problem with the installation beacuse my buddy had one of the guys from jet install it for me....I would stay away from jet.

I had the same problem with my hypertech and i found that it was the rev limiter. I was hitting the rev limiter before the auctal shift point therefore it wouldnt shift. Try raising the limiter higher and see, it worked for me

Hi guys. Been away for a while but my ex just said to choose her or my truck.........hmmm....sure like my truck..:)

Just spent that last month or so doing a lot of bolt-on mods, here's the list:

Gibson Extreme dual cat-back (noticeable SOTP gain)
Hypertech HPP3 (love the shift points but nothing drastic in gains)
K&N FIPK 77 Series (noticeable SOTP gain and cool sound)
Granatelli MAF (Is it doing anything?? Idle now is at 500....grrrrrr :wtf: )
Edelbrock Shorty Ceramic Headers (definite SOTP feel...painful install...re-use the old donut gasket...cheap b@s$trds)
Flex-a-lite Elec Fan (received wrong size fan last week...need the 292 for 28" radiator.....anyone considering this unit should measure yours before ordering a 282......mine should be installed next week)
Hypertech 180 thermo.....I'm sure my engine likes it..

Now.....I am wondering what next.....other than supercharging (we only have 90 octane in Alaska) I'm running my HPP3 at 93 setting with Octane Booster and no knocks or pings.
1.8 rockers? Is this worth the $$?
Custom PCM (I can sell the HPP3 pretty easily)....That Wait4Me PCM is sounding really good for $150
Throttle Body (does anyone know is this does anything?)
Throttle Spacer?
Nitrous?.....Anyone running Nitrous on an NBS?

Anything else......Bolt On....????? I need more power!! I can hang with Lightnings and SSs.....but still beating them depends on the situation.

I did not see a throttle body bypass. I have added one to my 4.8. I was looking for power mods when I came across this mob that was 17.00 and it freed up an average of 8 hp. I also did not see the flowmaster mmuscle truck exhaust. I just got mine and am going to add it this weekend.

Stg.1 EFI system for GM vehicles(nitrous express). 100 shot. It is a wet
system(don't get a dry system) that is adjustable from 50-150hp to the rear wheels. very simple to install. its pretty straigth forward. i installed a ZEX direct port injection for my buddies 2005 Honda S2000 and I can honestly say I never want to do it again. I would suggest you not activate the system for any longer than 15sec. at a time. If you have the system activated for too long at any one time you will melt the magnets on the solenoids. If that happens, the entire solenoid has to be replaced. You can run the nitrous as much as you want till your bottles dry(take this with a grain of salt, please!) as long as bottle pressure is maintained and you keep your runs under 15 seconds(i keep it under 10) then you won't have any problems. be sure to pick up the Iceman Pure-Flo nitrous solenoid(has purge built in) and replace the solenoid they give you with this one. it will clear your lines of all fluids(the nitrous will liquify when not under pressure and it will give you better performance). also, since your in alaska, i'd HIGHLY suggest getting a bottle heater to keep bottle pressure at 900-1050psi BEFORE it hits the solenoid. Try to keep yoru tanks(yes i 5lb tanks, one where the stock subwoofer was and the other on the other side, I'm very lazy and don't feel like removing them and refilling them all the time) at least a quarter full. you should pick up a Gen-x kit as well(so you don't "accidentally get high" off of medical grade nitrous oxide...on a side note. there is no difference in medical grade or the other stuff u get at gas refil stations. Just that non medical grade has a different element(can't remember what its called) that gives you SEVERE headaches when 'accidentally' inhaled. all you need is at least premium pump gas, colder plugs and upgraded ignition(i still need to upgrade the ignition). th ignition isn't a must, but would help. as far as activation of the system is concerned, you can go 3 ways. wide open throttle switch, electronic and push button. choose according to your driving style! for instance,I use a push button because my driving style is...well to piss off any many people as i can(i'm always at WOT). i stomp on the gas with the nitrous from stop light to stop light and sometimes flying down the freeway in the middle of the night. you can configure your set up all you want, even have the ability to change the amount of shots for every activation while you drive.

i will be moving up to alaska soon(hopefully), within the next 3 months or so. If you want I can help you install it.

K&N drop in filter and Superchips programmer (play with it a little - don't just accept the "performance" setting - manually adjust shift pressure and shift point settings - it is easy) cost less than 400 bucks and provides a noticible difference in my '01 5.3 Tahoe.

Just re-posting to this thread as well for the quickest response. Hey guys..............quick question here. New to the board and I figure this would be the best place for this question to be answered. I'm not new to the scene as I have a hopped up Grand Cherokee. My father has an 03' Burb 5.3 - He tows a trailer and wants a lil xtra power. 1st of all think intake, but he has heard thru people that with the oil type filters like K&N and AirRaid, mess up/contaminate the sensor that is located inside the factory piping ----- hense, replacing it once a year to the tune of $100. Have you guys had any probs with the aftermarket intakes and screwing up sensors and such or is it a load of crap? Thx guys

Howdy all,
Hope this thread isn't dead yet. I've seen several references to the throttle body by-pass on this thread. Never heard of it. I would like to ask a couple questions.

1) Is this applicable to an '02 6.0 liter

2) If so what is it and how is it done?

Thanks for any help.

1) Is this applicable to an '02 6.0 liter
yes, all 1999-2006 throttle bodies used the purge line to heat
the throttle body. this is a necessary item in 40 or colder
temps with humidity above 25%. itll prevent icing. other
than that, rip it.. who needs 220 inlet air?


2) If so what is it and how is it done?
a simple tube is placed in the hoses going to the throttle body.
this prevents heated collant from heating the throttle body
in turn heating the incomming air.
remove engine sight cover
remove air inlet tube to throttle body
remove throttle body from studs
pinch both lines going to throttle body
remove lines from throttle body
connect coolant lines to bypass tube (use existing clamps or
wrom gear clamps)
make sure the lines are secure
release line restrictions
reinstall trhottle body
reinstall air inlet
reinstall engine sight cover

tools needed:
flat-blade screwdriver
10mm socket and ratchet
pliers or needle nose pliers
2 pair visegrip pliers or girling tools

Hello all. I have a 2002 Flex-fuel 5.3L Suburban and I want to start modding my truck. So far I have a Magnaflow Cat-back exhaust and CAI. I want to know what I should get next as far as price vs gains

Airaid TBS: $100.00 I know it doesnt do much, but I could use a little more low-end grunt which I noticed on friends' trucks. And I have noticed you get a pretty impressive powerband over stock w/a spacer and the cold air intake
Spacer= low-end to mid-range
CAI= mid-range to high-end
:dunno:
Granetelli MAF: $299.99 (I've heard they do about as much as "descreening" the MAF so can't I just get the spacer, descreen the MAF, keep $200 in my pocket, and save up for the tuner which I heard works better with "entry level" mods already done?
Other suggestions in that general price range ($100-$300)?

I see headers but how about a section for Cat back exhaust. It is a power adder. I know there would be variation for dual/single exhaust but maybe we can standardize it some how.

Hey ya'll! I'm new here to this site and attempting to modify my truck for some power gains. Ya'll have some awsome mods to your rigs along with some pricey items. I am on a limited budget and would like to increase the performance in my "99" 5.3 Z71 without braking my bank account? I have already installed green air intake system and noticed a little increase in response and power. I was thinking about getting a programmer or doing a Nelson or Wait4me performance tune. Which one will control(eliminate torque management)? I hear that will release my engines true hp/tq potential?
Any and all suggestions/comments would be greatly appreciated!

Hey Guys,
I have just came across a killer deal on an 02LS1 intake manifold. Anybody ever put one of these on the 5.3?? I'm like 90% it would work fine, but what kinda power gains would I be lookin at? I don't wanna take the time to screw with that if i'm gonna get like 5HP.

I have an 01 silverado 5.3L 4x4. I have added the following:

Airaid intake
Ganatelli Mass Airflow Sensor
dual exhaust (but not catback)
Poweraid TBS
hypertech PPIII programmed
160 Deg. T-stat

What would one recomend next? Also I was thinking about a 3" exhaust and turn downs. Will true duals work on the 5.3 or will it throw a code and cause it to run bad. Any help on what I can do with my exhaust would be appreciated. I think I want to try
3" and turn downs, but am interested in advice from others.

I'm no pro, but I'm learning all I can. Your stock intake was designed for loads of tourque, like a truck should have. The vette/camaro was a little different. I don't know what would be required to put it on, but I would guess you would gain quite a bit of upper end power, at the loss of low end grunt.

Hey all... I recently put a intercooled procharger on my 2000tahoe with the 5.3, and I am just not happy with the power... maybe its cuz it has 4 wheel drive and the rig weighs as much as a small oceanliner... anyways the tahoe has 128000 miles on it and was wondering when the time comes to rebuild the motor, what could be done to either build it to handle more boost, or maybe just drop a ls2 motor in it??? any ideas

I noticed under cooling it had the electric fans at a cost of $400+. On Jegs I noticed they had dual electric fans for $189-209. Are these any good? The $189 dual fans are 12" at 2600cfm I believe.

hope im not dragging up an old thread but i just bought a 2001 silverado ext cab 2WD 5.3/auto to replace my stolen, never recovered first gen tahoe.

so far i only have crane firewire ignition wires (for an ls1 i think)and a flowmaster single in dual out muffler.

i am looking at some programmers but not sure what to get. im looking for improved fuel economy and hp/tq gains but i want to stay with 87 octane cuz i drive 60+ miles a day and gas aint gettin no cheaper.
i would like to find a used one or something less than $200 hopefully.

superchips has the discontinued max microtuner new for $200 on their website and ebay. it claims like 9-11 hp and 10 tq with the 87 octane tune.
is there something better? i read of the maxenergy hypertech and econ but are they worth the $380? is there that much difference over the hyper3 programmer other than being updateable?

i did some research on jet, superchips, hypertech, edge, diablosport, but couldnt find gain specs on all them. i assume some of them dont have 87 octane tune as an option.

(for now i think im try the throttle body bypass mod next since i live in texas and it dont get very cold here)

maybe someone on this site has a programmer for sale?

I think you'd be better off going with a custom tune. You can get it cheaper than a programmer with a lot more options and it's custom tuned to your preferences. Do a search for Wheatley or Wait4Me. There are more but those are the only ones I can think of right now.

correct me if im wrong cuz ive never got a custom tune before...a custom tune would be nice but isnt easily removable/reversible like a programmer? when i think of custom tune, its flashed in the computer or a new chip is burned and is non-adjustable settings afterward unlike programmers and arent dyno runs part of the process?
i found a superchips 2715 max microtuner new for $200 and a quadzilla stealth2 used on here for $200 also. i was thinking i could remove it and sell the programmer later if i need to upgrade so i dont think id save much money going for a custom tune over a programmer since i could sell programmer for close to what i paid for it since im only looking at $200. what does a custom tune run anyway$$?

im interested in small mods to add mpg and hp/tq. probally wont tear into the engine for a cam or heads or the like as i have a mustang project already where mpg isnt a concern.

I noticed your Spring, Texas. If you don't mind a little drive Xtreme Horsepower in Fort Worth does custom Dyno tunes. Call and ask them about removing the tune or dealer warranty issues. Their tuner, Arvil, is awesome they did my 83 chevy 5.3L swap. My dyno tune was like $400 so its not any worse than a good hand held tuner and its going to give you beter results.

Nobody has said a word about o2 simulators??? I guess most of you have inspections, but here in OK, we don't, so you can do pretty much whatever you want. I bought some o2 simulators of ebay for under $20. They are simply a resistor that will keep the a/f mixture where it is supposed to be, which is somewhere around 15????? You wire them inline on your o2 sensors, and then you can cut your cats completely off. My check engine light still comes on, but the mileage is good, power is better without the cats, louder, and best of all no replacing the $75 o2 sensors. Plus I can turn off the check engine light if I want with the programmer.

I have a couple Q's: first, what is this vette tranny mod??? I have the ability to adjust shift points and firmness with the programmer, would I still benefit from this?

Also, I want some decently priced shorty headers that DO NOT LEAK! Any suggestions based on experience? Thanks alot!

Your check engine light shouldn't be on if you have O2 simulators on unless they're not doing their job. I would find out what the code is for, might be for something unrelated.

Do a search for the 'Vette tranny mod, it's very common and others have explained it better. I also believe there is a write-up on how to do it and what it does.

I also believe that shorty headers aren't very beneficial on the newer LS style engines (99+), maybe someone can correct me on this?

From what I have read it's possible. Swapping LS2/LS6 intake manifold will require a wiring harness, because the wiring is in the front vs. the gen iii which is located in the front.

Custom tune, electric fans, long tube headers and your choice of an exhaust, put in lower gears to help with the bigger tires, etc. Do a search or start a new thread to get some help on exactly what you're looking for, willing to spend, and willing to do yourself.

Custom tunes are completely different from the "burnt chips" of yesterdecades. Do a search for custom tunes and you will find a ton of information. Go with a respectable tuner and you will not be unsatisfied.

so really what im asking is for the cheapest but simplest kit to switch to electric fans, and is it worth it?

Just what I was looking for, thanks

yes, all 1999-2006 throttle bodies used the purge line to heat
the throttle body. this is a necessary item in 40 or colder
temps with humidity above 25%. itll prevent icing. other
than that, rip it.. who needs 220 inlet air?


a simple tube is placed in the hoses going to the throttle body.
this prevents heated collant from heating the throttle body
in turn heating the incomming air.
remove engine sight cover
remove air inlet tube to throttle body
remove throttle body from studs
pinch both lines going to throttle body
remove lines from throttle body
connect coolant lines to bypass tube (use existing clamps or
wrom gear clamps)
make sure the lines are secure
release line restrictions
reinstall trhottle body
reinstall air inlet
reinstall engine sight cover

tools needed:
flat-blade screwdriver
10mm socket and ratchet
pliers or needle nose pliers
2 pair visegrip pliers or girling tools

TB spacers are kinda useless on anything newer than a 96. Also descreening the maf will get you nowhere. A CAI and a set of long tube headers are your best bet in terms of cheap bolt on performance. I would also get a custom tune as well, money well spent.

The truck doesn't have a muffler, so it's stupid loud. However, I know several people who are running LTs and a larger muffler and their trucks are fairly quiet, a little louder than stock, but not by much. Or you could just do the heads, cam, exhaust, and tune on the LQ4 and have one beastly truck.

I have a comp 212/218 cam in my truck, ran it quite a while on a stock converter and made pretty good power. I have heard quite a few guys go with a 220/220 cam on a stock converter as well, but that's getting to the big end of the useful spectrum for low end power.

^This. I put an Airaid MIT intake on my truck (tube from stock box to throttle body) and saw no noticeable gains. Only difference is that the engine got a little louder and I now think it looks cleaner under the hood.
