    Supercharger LS

    Hello,
    We've been having drivability issues with a supercharged. It has a Magnuson blower, 3.2 pully and 17113739 injectors. Initially the fuel pressure was set at 38lbs. O2s don't read while logging would like a second set of eyes on the file.

    Thank you.

    Do you have a log?
    What is it doing? Fuel pressure should be at 58# for those 42# injectors. Then you will need to re visit the IFR, and probably retune MAF and VE table.

    In both of those logs the o2's and fuel trims were working correctly
