My car ran out of fuel on the dyno at 4k rpms. It started to lean out bad. That was with a walbro 255 intank pump, 60lb injectors, aeromotive fuel rails and aeromotive FPR. I had to buy an inline pump, bigger fuel filter and a -6an fuel line to fix my problem. Now its all good! Ideally the best set-up for us would be an 03 tank so we could run the two pumps. I really wish i would of bought Slash's when he was selling it.
