I'm looking for a little direction for tuning a 4L80 for a street/strip F1A powered car. I have Hptuners and been looking over there but there's not much info on 4L80 tuning. I will hopefully be putting down over 750+HP. Does the line pressure have to be 90 or can I bump it up to 125-150psi to help the clutches survive? Any and all help will be GREATLY appreciated.

As far as line or trans pressure goes I see that almost everybody say to leave it at 90psi. I also need to know how to set the trans up to perform a burnout. These cumputer controled transmissions takes some getting us to lol.
