Well I I got my truck tuned on friday and I found out my problem. Whenever I would get on it hard and start building boost about 3500 it would just fall on its face like the belt was slipping on the blower. I checked the belt and everything I knew to check and could not find anything. I had an appointment to get it tuned so I figured Iwould let them check it out. Turns out that the hose on my fuel pump was busted so whenever I would get on it and it tried to get more fuel it could not get it just blow it out the busted hose.

Well needless to say the truck is running like a madman now The best part of the whole trip was the ride home. I was coming through town and a little honda pulled up beside me and a guy in the passenger seat was pointing at my truck and laughing. I just looked at him and smiled he said lets go next light I smiled and waited for him and the next light a good while HAHAHA
