Torque Management: Pics of how it works

My question is, if I get a Westers tune and have it run on 89 gas, will I lose or gain gas mileage?

My truck is almost identical to vhato's: 2004 6.0L w/auto Crewcab, Shortbed.
I'd love to have more power at WOT, it just makes noise now, it doesn't go anywhere!!


Thanks.

P.S. The Predator is almost 1/2 the cost of the Westers, will it remove TM? I'm not looking to drag-race the thing, just need more power for towing and getting on the freeway...

Based on what you wrote I would guess you will see no MPG improvement with a Programmer or Custom Tune. You will just notice you get to driving speed faster. The fuel improvements will only occur if you keep your engine revs around 2000 RPM and not to exceed 2500 RPM in any gear. That should be acceptable power with moderate gains, but the fun of the extra power won't be there.

BTW,

SWEET A$$ HD. Do you have any other pix? I went a few weeks ago when I saw another post but the pix would not come up.

Hey vhato,
Do you know if the AUTOTAP works for some parts on the duramax? Or is there different software for the wonderful world of diesels?? I have a 5.3 and my dad has a diesel--if it will work, i think he will be interested in buying that program. If not, then i am SOL haha.

Thanks,
Matt

AutoTAP will show data from all aspects of both Gas and Diesel. That is it, only show data. It is a valuable diagnostic tool.

Ok whats better the Predator or Pro-Flash? Who removes all the TM without a custom tune? I want a handheld unit so I can remove the tune if I have to go to the dealer for warranty work.

[vhato]

I really do not know. I held off buying the SPE Proflash because I saw the Predator was customizable. I didn't buy either one of them. The SPE Proflash appears as if it removes a SUBSTANTIAL amount of TM, but I dunno how much. I want at least 80% removed.

I too would be interested in a programmer, as I'm afraid to go to the dealer with a Westers in there. Not that they would say anything about this programming, but one reflash and it's all gone.

P.S. .....Anyone able to spin their tires just nailing it from a light with a 6.0 in a HD??? As spunky as this engine is, it's DEAD off the line.

Is that why my stock 350tbi rcsb 5speed that only dynoed at 190rwhp can out run my buddies 02' 5.3 from start to 99mph? His truck is rated at like 285hp. He has a rcsb and a 4l60 with 3.42's i think. As soon as he got his hypertech and cold air intake he could catch up with me at about 90mph and leave my ass in the dust.

[vhato]

Mostly yes.

[Hellafast91]

That sucks. I would have to do away with torque management if i got a new truck.

[vhato]

I have since learned Torque Management comes in 2 flavors. Engine TM and Transmission TM.

Engine TM is used to limit Torque and HP for the most efficient emissions.

Whereas Transmission TM is used in conjunction with Engine TM to protect the transmission.

I own HP Tuners and a G-Tech Pro RR. I will remove 100% TM and chart it to see any loss as well as using the G-Tech to chart any HP gains using 2nd gear. Next I plan to remove 50% Transmission TM and chart the same gains.

Stay tuned.

Yea i plan on getting hptuers and getting rid of atleast 50% of TM
Now also i heard if you remove too much you can start damaging things.
I guess this is the reason i can smoke the tires from a stop sometimes then all the sudden errr.rrrrr.r...rr.r.r throttle is killed and then 5 seconds later it returns.

Bingo!

Taking out 50% on a stock tranny would be perfectly fine. If you plan on going more I would suggest getting a shift kit and upgrading the servo's to the corvette or billet if you want it even more firmer.
I've been running mine on either 80 or 100% TM removed (can't remember which) from Texas Speeds tune. It feels a whole lot better now and it seems fine but I wouldn't recomend it unless your planning on a new tranny like I am.

I really don't buy into this whole talk about removing torque management completely being a guaranteed early death of a transmission... My 95 was putting out considerably more torque than any 4.8, 5.3 or 6.0 with only minor bolt ons, a tune and TM removed, and that transmission acted like-new when I sold it with 110k miles on it. Stock 4L60E with the same (if not lower) torque and hp limits as today's 4L60E. And I in no way babied that engine & transmission...

I do agree that a shift kit and/or vette servo is definitely a wise move with removed TM, but not having one won't mean instant death to the transmission...

I agree, I think they (GM) put it in for a couple reasons.....

1. EPA reasons somehow to "gain" some MPG's.

2. To create less broken drivetrain warranty claims.

Ok, didn't mean to say that removing TM on a stock tranny was instant death. Just that it is more prone to wear & tear/breakage. Like I said my tranny has been fine since remove my TM too and its still stock w/ 85K miles.

Sorry if you took it that I was referring to your post directly, I wasn't. Just was commenting on the general "karma" about removing torque management on a stock transmission, both on this site and others. 6 years ago, no one had heard of TM. Just crank up the line pressure and you're good to go... and now it seems that any post about removing TM results in people being scared away from removing it without doing a shift kit...

hmm i might have to add this, i hate the AWD system on the denali on dry pavement since all itsdoing is killing my gas milege, and eating up my mud terrains lol. For a truck with the HP/TRQ numbers this truck is putting out w/ the 6.0L my old 99 tahoe before my custom built engine in mostly stock form with a few bolts ons felt like a vette compaired to this truck. I had no problems smoking the 38's on my tahoe whereas now because of the TM and AWD i cant even spin the tires

DenaliTX, your 02 Yukon Denali uses the same NVG149 transfercase that is used in all the Sierra Denali's and the Chevy SS. It will get the same gas mileage as a 4wd truck will running in 2wd. Most, like myself get 12.5-13.5 around town and 17 or more on the highway with a custom Wester's tune. Stock it was 11.5-12.5 ans 15 on the highway. Be glad you have an 02, because in 03 the Yukon Denali went to an open center diff and uses the brakes to slow the spinning wheel to give the AWD and Performance suffers. Get yourself a custom tune, Wester's will remove the TM to a safe level, I can't vouch for the other tuners, and will ge you much more power and throttle response. Don't expect to be doing burnouts with the AWD though, it is an excellent AWD system and has the ability to transfer 0-100% of the power to the front or the back. It works like a front to rear positraction.

[DenaliTX]

Sounds like i am going to get the tune..especially now that im talking to ORU and a few other companies about bolting a 9.5" kit and 38's on the beginning of summer after this semister ends
