I have found that my fuel pump cannot keep up pressure after I have been driving my car for long periods of time. Your fuel problems have been plaguing you just as long as mine have been plaguing me. I will be getting dual walbro's soon, that should solve my problems. The stock injectors and rail appear to be able to handle a lot more power than perviously imagined. I'll surely keep you updated.
yeh I was thinking about the fuel pum,p also since my car runs pretty smooth and idles good also. doesnt seem like my injectors are going bad at all. simply fuel starvation.
are you keeping an eye on your A/F?
