If the torque model is off (yours obviously is) then the TCM will not understand how much power you’re making and the trans will not deal with that for long.

Not to bust your chops, but I probably would've been asking more questions about three transmissions ago. |

I think Josh is correct. Does the car have meth injection?

  I think I’m right too. A Procharger doesn’t hit the trans nearly as hard as a PD blower, and yet there are tons of us PD guys still running stock A8s. Chewing up FIVE A8s is crazy.

Yeah I agree and most Procharger guys seem to run Meth. My guess is the Virtual torque tables are not setup to compensate for the meth and that will burn up these transmissions fast.

I know the car, he runs at our track and they've been thru a bunch of trans for sure. I dont' think the car has made it out of the 10s since its had so many trans issues. Its sound really nasty and everything else seems really well built.

 . I want to reach 900 whp and i'd guess around 770 lbft. I believe i have a great tuner so i trust his capabilities.

The key is the tuning. I’m sure I’m leaving some time on the table by leaving the torque management on, but I’d rather that than rebuild the transmission every weekend…. If you want full power shifts you can do it, but it’s $6K to do a hardcore A8 build.
