How much line pressure do you run on your built or modded 4L80E? I started out with the stock tables and the trangso shift kit and its firm but no where near tire chirping and the 2-3 shift is kind of lazy. I raised the line pressure slightly and it made the 2-3 shift better so I raised it by about 33% overall and now have a max of 90 psi at WOT. Its plenty firm but I was just curious what kind of pressure you guys run to keep those clutches from getting smoked. Does anyone know what the max regulated line pressure is stock for the EPC motor?
