It probably sounds like a broken record but here it goes. I was out tuning my car today and when the boost would come on my fuel pressure would start dropping off to about 50psi. I have the reg. set at 44psi vac. line off. I increased the press. to 48 psi and still would drop off. Boost is set at 20 psi I got 009's. My 02 numbers started about 820 and dropped to 740's then I lifted. Luckily I had zero knock. What the hell would cause this?? I've got a new XP pump from Red, hotwired, adjustable regulator, volt booster. I was watching my scanmaster to see if the voltage was dropping but it held steady at 15.2 volts at WOT. Changed my fuel filter just in case but nothing.
It runs like a bat out of hell but hows that saying go: Leaner is meaner till you blow it up!
What gives??
