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.

What does your wideband 02 read when this happens?

 

is the fuel pump straight to a relay?

 

Ok so I was like at a quarter of a tank or smaller how do I check this fuel tank thing bc I filled it up and now its fine!
