Re: fuel running out at high RPMs b/c of stock fuel lines
Those stock fuel lines can support up to 500hp. What cam are you running, and do you have any tuning device? With a PMS or FAST, you can alter fuel in the RPM range..Did your tuner say what % your injectors were at in the high rpm range and what was the air/fuel ratio? What is the fuel pressure set at? You mentioned boost but nothing about a blower or a turbo, more info? Boost will tend to blow out the spark as well, be sure to lower the gap on the plugs, MSD will work wonders as well.
