I have a 05 powerstroke on which i just installed PPE tuner and a 4" MBRP exhaust.
When I "encourage" the truck to go fast, it makes a loud whooshing noise, it does not do this unless i really get on the throttle. It also seems to lose acceleration whenever this noise is present, but the boost gauge doesn't change. A buddy of mine told me it was the wastegate, but I figured I would get an expert opinion. Has anyone else encountered this issue? It is normal? Or is something wrong?Before anyone says its a leak, I have checked and re-checked all clamps and pipes and it sounds as if it is coming right from the turbo. Thanks!
