how much fuel pressure at the fuel rail?
I have a procharged zz4 with tpi. 255 fuel pump and 42# fuel injectors - a guy who is helping out on the car asked me to see if I could find this out - how much fuel pressure is there supposed to be at the fuel rail?

Re: how much fuel pressure at the fuel rail?
I have a zz4 also with a mini-ram set up with a who bunch of other add-ons and I talked to a guy at TPIS and he said I need to be at 70 PSI. If i set it lower in the 40's my engine misfires like crazy, is this normal?
