Default Peak torque at 506ft lbs (6AT) anything to be concerned about for trans longevity? - 10-15-2020, 11:29 AM

I just ran a dyno on my car, and my peak torque is topping out at 506ft lbs. (09 135i 6AT, full bolt ons, e85 and custom tune)

Is the trans okay to handle this much torque? I'm a bit concerned on longevity.

Dyno is attached

yeah probably fine until you get to IIRC 600+ wtq, that can be when problems show up. Get the TCU tuned. Do trans svc if you havent (pan, fluid etc), and consider the valvebody/solenoid kits for peace of mind.
