I have a 04 f350 with 80K miles and recently i noticed when i really get on the pedal and push the truck into overdrive I get what sounds like a rush of air I am assuming is coming out of the air filter, my boost gauge intermittenly shoots up to 30-32 psi no black smoke, and no gain in power when the boost rises but no power loss either. It has only happened twice once while towing up hill and the second time with no weight but heavy acceleration. After looking around I noticed that this may be referred to as turbo fart but most people seem to drop boost when this happens not gain it. If anyone can provide some insight that would be great I have plans to pull the turbo and clean it but not sure if this is normal or I should also look somewhere else.
