Torque management

[02_Tahoe]

I've done tons of research on this across 4 or 5 different forums but still can't find a complete answer. All threads say it reduces torque during shifts, but is that all it does? Does it affect torque when stomping the gas from a dead stop because when I do it I can't even get the tires to chirp, it could be that I have new aggressive 33" ATs but when I had smaller bald ATs that looked like drag slicks I couldn't even get them to chirp. I have the 5.3, 3.73 gears, and a flowmaster exhaust. If torque management is turned down will it help with off the line power

I feel like someone from Blackbear might know? I've heard something about a corvette 1-2 solenoid or something like that, but that's a problem a lot of us have, WOT doesn't do anything from a dead stop.

FWIW- I did a diablosport tune and turned off Torque Management, the result was more positive shift from gear to gear (less 'slippage, or quicker engagement).

Well my question is about power from a dead stop. It doesn't feel like it has much so I'm asking if taking away some of the torque management will help the power off the line

From what I understand, torque management is only in place during shifting.

You have a few things against you coming off the line....heavy vehicle (5200 + lbs), tall gearing and tires (need 4.10s or 4.56s) and a basically stock 5.3 (or could be a 4.8???). All those things conspire against getting your Hoe moving.

Cheapest fix would be the gears, even if you're 4WD. I have 4.10s in my Yukon XL from the factory, makes a huge difference.

From there, you're into engine mods, higher stall converter, etc. No real way to make these things any lighter

With 4.10s how is highway cruising? Like how high are you revving for 75 or 80?

Is changing gearing easy, like is the average person who has a decent amount of skill with mechanical work able to do it in their driveway

I see around 2100 at 70, drinks too much gas at 75/80MPH!!

You could, especially if you're 2WD, If 4WD, the front is going to be a PITA!

Well I am 4wd. Do I have to drop the diff in the front to change it

 

[deerhunter1970]

Yes, the entire diff has to come out for a front gear change

That's past my abilities. What do you think it would cost to have someone do just the front. I could do the back and take it to a shop for them to do the front

Don't really know, especially in your area. Figure $80/hour labor, and probably 4 hours (maybe more) + the actual new gear $$$.

Probably with parts, your're looking at somewhere between $500 - $800 per axle. Depends on the quality of parts/$$$.

Yukon gears with all the small parts is $400 for just the front.....

I can get 4.30 gears for $240. I'll look at videos on dropping the front diff for my truck. It can't be that hard

Taking the diff out isnt hard at all. Its pulling the entire case apart to get the carrier out thats a pain in the ass.

 

[Mr. 960]

I have an 06 Sierra 5.3 with 3.73 and it lights them up easy. If I stay on it my locking diff will lock in and spin two wheels. My 06 Yukon with 4.10, 4x4 and a 5.3 will only chirp off the line with 275 70 17 Cooper AT3 tires. Going around a turn it will break them loose. It is all about weigh over the wheels. I should mention both trucks have been dyno tuned but have always acted the same right off the line.

I don't know bud, if you never set up a rear before i would just let a shop do it, just to be sure you dont blow it up. I do everything myself too but ive never actually pulled the rear apart....im def no mechanic but afar as ive gone (comfort level) is splitting them (pulling axles) not saying its hard or easy just dont want to see you have issues.

Yeah I watched a few videos on how to do it and I think I could do it but i don't have the tools and don't want to buy the tools to use once. Right now I'm a senior in highschool and next fall I'm going to a technical college for diesel technology. So I figure I'll just wait till then since I'll be learning how to do these sort of things and the school should have the tools to do it.

If you have someone do a custom tune, this can be removed. It does affect WOT launch. Just had it done on my 07 Escalade. Huge difference
