With 25.5 psi, 24 degrees, 110 octane. A/f ratio was 11.3:1. Wanted to go to 29 psi but couldnt with wastegate configuration i had that day. P-trim turbo and stock screened MAFS killing the combo. It was done on the stock ecm though and the converter was eating up a bunch. Worked GN1's, forged crank, FAST SFI, 70GTQ and probably a new cam going in within 2 weeks after return from BG. Should go 650RWHP at 25psi with no problem if i dont drive through the converter and even more at higher boost pressures.
