It depends on how much boost I wanna push. I have the fuel set at 300 and -30* on the timing. I can build 20psi but with no fuel or ignition adjustment it's at 32*
At the track and going threw the gears without spinning it's make 11psi. From a roll it will go to 15psi. I have 2 44mm wastegates.
Nope waiting on slicks
