[crawfish]

i did my first tune on a friends truck and now sometimes when the throttle is pushed it starts to roll then u can press to the floor and stalls for a few seconds then takes off and tranny hits very hard can't figure out what i've missed

man i had the same thing it was the torque management set to zero. or start all over and save time. good luck.

it's almost like theres a dead spot in the petal switch, today i drive it and was cruising around 30mph then pressed the petal slightly and no increase in rpm or speed then put to the floor and stayed that way for 2 blocks then it took off ??????????????????????

Sometimes its best just to back up to stock and start over a couple tables at a time until you run into the problem again...

[oakley6575]

I would do the same thing. Start from stock and make little tweaks in the tune until you're happy. GL

I know what it is. Under torque management, disable throttle tip in torque management. Problem cured.

I was looking the tune over today and did change. The tip in torque back to stock I'll upload new tune to truck in the morning and post my findings.

[crawfish]

that be a big negitive, problem not cured ive installed same tune on another truck and no problems if i install stock tune on the 07 no issue? i've noticed a petal relearn button on the scanner but not sure what it's for i sent hp guys an email about the procedure and they didn't know??

Reread the post I know we're the damn button is, how it's used is the problem

[crawfish]

Sorry for the attitude but when I pay this much money for a product I expect a Lil more tech support from the guys who work/build/design this product if there's a option for this button to be on the vcm scanner you should be able to explain the procedure for it's use

did you e-mail support?...

[crawfish]

Yes I was instructed to contact gm dealer for the petal relearn process and that's what I posted earlier, just frustrated I had the software dam near a month and read more than 3 hours a night before I even did a scan on my own truck because I didn't feel comfortable with the tuner yet and first truck I plug the hptuner in to other than my own something weird is happening and no one can figure out the problem, I've since put truck back to stock other than shift point and still does same thing if totally stock tune put back on no problems????

[crawfish]

Late night I left the tranny tune on and replaced everything back to stock and runs fine I guess I'll go little by little then I may be able to pin point the problem thanks for everyone's input

[IDRIVEAG8GT]

Did you DISABLE the tip in limiting?!

The 07 OS is not made to handle the tip in management.

[silverado08]

I'm experiencing the exact same problem did you find out what exactly did it ?

[TexasGMC08]

The issue is in the TRANS> Tqmgt > Abuse Mode> leave stock don't Zero them out Truck or Car.
