Does anybody know who in the NY/NJ area can still tune or look at a Diablo chip? I can also send computer out if that is an option. I have a 91 Mustang with a Kenne Bell s/c and a old school Diablo chip. Car starts and runs great until I turn it off. When that happens with the key on engine off the fuel pump keeps priming and I can kind of get it to start but it is a mess. I can let it sit for a day and it will run perfectly again until the key is shut off and I try to start it again. I have changed the fuel pump relay under the seat and replaced the tfi module but no good. I pulled the computer and had the capacitors replaced which were bad but still no good. My only thought is possibly the tune is corrupt. The guy who did the capacitors said the tune is protected so he could not check if it was corrupt. Any help would be appreciated as I can't drive the car because if I shut it off I can't get it back home again.
Kenne Bell s/c @ 10lbs, 30# injectors, 255 in-tank, 90mm lmaf, 4" Anderson intake, Magnaflow exhaust, Diablo tune.
