HP tuners help
So we made some progress on the 01 suburban with the 8.1L
Torque management is not off, Drive line protection is now off, and so is throttle delay.
Some how, I have developed a problem. The truck 17.4 stock. with the parts / tune its running 17.9 ( ill get the time slips and post the difference) anyway it launches and runs excellent in first. Shifts to second and doesent want to revve, you can watch the tach stop moving, but the spedo still goes up. once its out of second it pulls very very strong in 3ed.
Whats strage is it only does it at the track. If you hammer it for a roll its fine, or if it down shifts its fine.
So is there something that would regulate the acceleration at the track? I launch it on the foot brake at about 2200 rpms.
I didnt have the computer with me at the track but on the highway it data logged the truck is delivering 456lbtq...
