Power mods of 99-02 5.3 V8

[scorpionwv]

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.

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

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

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 have a 2000 rcsb 4.8 volant intake superchips prog. flowmaster single what else should i do ,free mods or low cost for light to light power?

[turbogunz]

4.10 gears and a powertrax or true trac

[yz250roost]

I've got the Airraid and can vouch for it's power increase. An outstanding unit!

[NoSelfEsteem]

Im Not ASE Certified but AEM Brute Force Intake $379.99


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.

[dsf81]

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.
