Torque Management

[Kenny D]

I apologize if this has been discussed before. Do all the NNBS Tahoes/Burbs have torque management?
I have an 09 5.3L with the 6 speed. If so, should I dig into my Diablosport tune deeper and turn it off?

"Yes" and "If you want to". Reducing and or eliminating TM results in more power "remaining" available to be put to the ground, but also results in more drivetrain and driveline stresses. You play, you pay. BTW, I am in NO way advocating leaving TM alone. My recommendation is to reduce it but not totally eliminate it.

Thanks, I will play with my tuner and see if they offer a percentage reduction. It just feels like something is holding me back a tad on take off. I'm not talking about stomping on it from a dead stop, but when I need to pull out onto the highway from my neighborhood, I feel that the 5.3 should pull a little harder.

A very respected tuner told me to turn the engine TM off and take out 75% of the transmission TM

I only have the option to turn off the Upshift TM in my TCM. I opted to just leave it alone until I can research further.

I just recently tuned via diablesport i2030, of which I turned OFF the TM, different is noticeable (or I think it is...hard know exactly when you do a tune as you change many things all at the same time)...anyway if anything I have noticed it mostly at passing speeds just being more engaged and less lag.

note; I believe there is also TM on the tranny screen as well, this I left alone for now.

Metelhead, what year? I did not see an option on my tuner 09 5.3 other than the TCM one.

2009 LT....all I remember was the screen wasn't what I was expecting to find when I open up the module...I was literally just scrolling thru all the perimeters of i2030 and kinda stumbled upon it...might ask on the diablesport forum for specifics

Interesting. I'm getting an in-person BBP tune in may and will be curious to cover this.

I'm no stoplight racer anymore, and I'm not interested in thrashing my driveline. Just looking for optimal drivability and responsiveness from my daily driver.

Responsiveness is what I want as well, which is why I'd have a trusted tuner (such as BB) adjust the TM. They have enough experience to know what can be removed to improve on or completely eliminate the sluggishness while maintaining some sort of protection, if any is desired. Personally, if I wanna be easier on my drivetrain, I'll have to control my right foot. I don't want a computer to determine that I'm being naughty and deny my request for power. If something breaks, it needed to be upgraded in the first place.
