Is anyone running an auto transmission and a jb4? I noticed if I disable Watergate adaption/learning in jb4 settings it limits traction intervention and allow jb4 to have more boost control. I can power through corners better and put more power down in the straights. Apparently, the car controls the wastegate even with a jb4 installed which will limit boost. My car is loading up the suspension more as the car leans or rolls more in corners on the front tires and rear tires. I haven't seen outer treadwear in a while since abs/traction keeps the car on all 4s pretty good with very little pitch.

I'm really not sure why all of this is happening but it feels nice. There is still some intervention with steering angle in extreme cases which is good. Your not really going anywhere safely with too much loss of traction.


Can someone try this out and post results.
