    What RPM are you running... are you monitoring a/f... why do you feel that 50's aren't enough???

    @8600 RPM ,and yes I have a A/F ,the 50,s was real lean at 75 pound at 1800 Rpm and 13.5 at 8600 and every time i give more gas the injectors was going leaner ,i went today to injectors clinic and got some 60 ,that was what PPG used all the time ,i will go on the water tomorrow but i like to have my RRFPR set first at what point?

    Sounds like your 50's are locking up at high pressure! Hmmmmm.... Delphi's

    Sounds like you just need a set of BOSCH 50's!
