Why?BMWERKEN said:Well you have to be aware of the fact that the step tranny can only handle 270 torque and 310HP...so if you go FI, most likely super, u can't bump PSI up to produce such levels of power...

Has anyone had one fail and taken it apart to see what failied?
I'm wondering if line pressure can be turned up to increase clamping force? Maybe something as simple as an aftermarket oil cooler would do it too.
Has anyone looked into using any of the million shift kits / valve body mods for GM trannies?
Betting BMW set it kind of soft so the shifts are "smooth" but generally stuff like that can be easily fixed.
