> Thanks man, the first curve before 7500rpm was the 35psi spike. Then the dip and the rest off the curve to redline is 31psi, all it would hold. Really should do stiffer wastegate sprigs and hold 40+psi but my injector duty cycle was mid 90% IIRC so I’ll wait until I get a better fuel system.

ok, nice, i had the same “dip” on a car that i was tuning . My timing was off in one cell, but it could be alot of other things, fuel pressure dropping off…etc Be sure to log each pass at the track so you know if something goes worng quick. good luck!! i knew you make 700+…get a bigger fuel system and you can make 100hp more with the same turbo.
