My current boost pressure is at 8.8 PSI making 460 WHP and 380 Torque on dynapack dyno
PS: This dyno reads verrrry low that a stock GTR produce 412 WHP and stock 370Z does 230 WHP..

Here the interesting part... UpRev really did a great job cracking the transmission line pressure to make the tunners tune it.. I mean seriosuy without increasing the line pressure.. there is no use for FI for AT

When my tuner first recieved my car, he spent a lot of time fixing the AT slipage, it used to slip every single time he give gas and the only way to make the car back to normal is to turn the car of and turn it on and everything goes back to normal.

But right now after 4 month of usage the transmission is holding the power realy great and the shiting had been waaaay better than before its almost semi gtr's transmission (not that close but its night and day different in shifting)
