Hey all, maybe someone can help me out. I recently picked up an 87 4 cyl conversion , its a 5.0 stick car now. It ran real good, but I wanted a little more. I put on a home made twin turbo kit w/ 76mm turbos. It not finished yet, I still have to put some downpipes on to complete it. I fired the car up and was going to take it for a nut ride with open turbos, but when you stab the throttle, it revs 3500 rpm then falls back off back to idle. I pulled it back in the driveway, with it in neutral, stab the throttle, it revs 3500 and falls back off. If you ease into it, it will rev 5000 but when you reach a certain spot on the pedal, it falls off and won't come back until it goes back to idle. Here is a little more info on the car and mods. I replaced all the gaskets ( heads, valve covers, intake, pan), installed 42lb injectors, 42lb lightning mass air, electric fan, 4" core intercooler, twin 76mm GT 3076R turbos, disc brake rear w/ 3.73s. I haven't upgraded the fuel system yet, but I checked fuel pressure and it doesn't fall off with the rpms, it maintains 38-42lbs at all times. I have been beside myself because I can't figure out what is the matter. Any help would be greatly appreciated. Thanks in advance,
