mine did the same exact thing but I have a little more done than you. I would also like to know whats up. Im adding another pump but would like to hear what everyone thinks about yours so I can check mine also. Good luck!

I have a 255 intank w/hotwire kit, 60lb injectors, stock lines and rails. tr224, full boltons w/12 bolt, and d1sc. Car made 565hp at 5200rpm due to it leaning out. The guy tuning it said I needed to add another pump, which I ordered already but also wanting to hear what everyone else thinks. Thanks and not trying to hijack the thread but it sounds like we are having the same exact problems.

Do you still have the stock injectors?Outside of suppling fuel the pump doesn't have much to do with it running lean looks like you need bigger injectors or get the tune setup to increase pulse width.
