#75504, "back firing at high RPM"


          

Hey I just dropped in a freshly rebuilt stock engine into my GS. I have the Star Stage 1. currently im running 5 PSi. When my RPM's get to about 5 I get a back fire. Could this because I need to upgrade my fuel pump? Or Injectors? Any and all help is appreciated. Thanks guys
Jim

What kind of egts do you see with this setup? Have you done a boost leak test? Are you on stock injectors? You have the 255 fuel pump, what fuel pressure are you running with this?


400whp or bust.
