I have a '97 Powerstroke. I had a reputable turbo shop upgrade my turbo and after installation my 7.3 started missing under load. It's worse after it's warmed up. Fuel pressure is a little low. Under a heavy load it has 19 lbs of boost at 1200 EGT. I have a TS Performance 6 position programmer set at 75 HP. Is the fuel pressure the problem? It didn't miss prior to the turbo change.
