Question on possible Fuel cut?
OK i have a 93 fd. Everything seems to be running fine until im running down the road in like 3rd or 4th and start to build boost and it pops once i get up to about 10 to 15lbs of boost! It almost feels like its fuel cutting but i have no idea why? Ive checked everything i know to check any ideas? Heres my build list if it will help>

How full is your tank when this happens? If Steve tuned it on the dyno and it didn't have this issue and now it does, I would bet that it's because you have a 93 with "fall apart" fuel tank baffling and when your fuel level is low the pump pulls in air under hard acceleration.
