Problem solved thanks to help over the phone from strictly diesel. I was buying a boost gauge from them for testing and person on the phone said hold on talk to one of my tech about all the stuff you have already done to you truck to find why you have a low boost pressure. after every thing I told him he asked me if I had the turbo recently I told him that I had a dealership install new up pipe he said that probably it what it I said they knocked off the exhaust damper linkage that is exactly what I found so thank to every one for the help and the guys at Strictly Diesel.
