[QUOTE="XXWildCoyoteXX, post: 15624169, member: 154827"] Currently tuning my Mach 1 and my tuner has come to this issue and is wanting me to figure out the issue. He is thinking i may have a poor quality regulator, line restriction, or regulator isnt seeing correct vacuu/boost. What he is seeing is a drop in Fuel Pressure at WOT, 5 psi to be exact. It seems to him its falling off with rpm so it possibly could get worse over 3500rpms. Setup: Lethal Performance Budget Return fuelsystem Stock Feed Line Stock Fuel Rails 60lb injectors Dual Walbro 465 pumps -6 Return Line Lethal FPR with FPS attached All this is running with a Cobra Engineering GT500 swap kit, so my boost reference for the bypass and FPR/FPS comes from the back of the Cobra Engineering plate, right above the rear drivers intake runner. Any useful info or help would be great. Thanks [/QUOTE]
