good info, tonight i noticed when i hit 100 and shift to 4th it wants to fall on its face, if i let off and get back into it, she keeps on going fine....had it up to 120 and let off. Could this be because of torque management I read that its ruff on 4th if you shift into at WOT. So i thought maybe he had it tuned to back off the torque at 4th shift point. Idk if this is even possible but it sorta makes sense to me.
