7.3 turbo problem

I recently bought a 95 powerstroke my first diesel truck. When i go to start the truck my turbo makes a loud blowing noise it would always do it for a few seconds right after start up (when cold) but then it would stop. I always let my truck warm up for 10 minutes and it continues to sound like a jet blowing air. When i start driving the truck it will go in and out out of this and looses power unless i got my foot to the floor. A buddy of mine says it could be the waste gate but we couldnt find it ????

Sounds to be your ebpv (engine back pressure valve) totally normal for it to do that. It is controlled by the PCM to help the engine warm up quicker. It is a flap after the turbo that closes off the exhaust creating back pressure making the engine work harder. It can be unplugged if wanted to stop working or if it's a five speed it can be made to be controlled manually for a exhaust brake or it can be totally deleted out of the system or left to be automatic controlled by the PCM

It is a 5 spd what would be the most sensible thing to do just delete it. Where could i unplug it its just real annoying. You think if i give it a lil tap with a hammer that would help lol

Haha hammer might work but might take something else out and that would be sad lol, well mine is hooked up as a exhaust brake but lots delete it so that is a personal choice on that one to unplug it there is a plug that is attached to the compressor housing (intake side) down low on the housing that you unplug to stop it from coming on.
