Depends on how much torque is being delivered to the trans. Anywhere from 0PSI base up to 90PSI.

I was using HPTuners to reprogram my PCMForLess tune and the base had been set at 136, and the recommended max is 96 and I was just a little confused/worried.

These are the factory baseline settings for the 1-2 shift
