In late August I was driving my '03 and pulled out to pass and my boost would only hit 26-27 psi. Usually my truck would do 35psi+, (35psi gauge should have 40psi gauge). I thought my small vice grips fell off of my wastegate line as that is what boost pressure would do prior to vice grips being added. I was too busy to investigate things further thinking it was an easy fix I wasn't too worried. The vice grips are in place. To eliminate the chance they were letting air thru I plugged the hole from the boost elbow. The next thing I investigated was a possible boost leak, I found a small one at the intake horn. I fixed the leak but the same problem. Only 27 psi and 1050-1100 F on the pyro. Thinking I was maybe lacking fuel I changed the fuel filters on my FASS. Still no improvement. Today I loaded the performance program on my smarty Jr and boost was the same but pyro would hit 1200 F. I had more power but my boost gauge would not go above 28. My SOP dyno is telling me things aren't right. I shouldn't have a boost leak as my egt doesn't get too hot. I'm thinking my turbo isn't giving me enough air and thus the Jr isn't giving me the fuel to get me to ~37 psi and 1200F.

Can the wastegate break?
What could be causing my low boost and thus low fueling?

I'm thinking I'm going to inspect the turbo a bit more. It really stinks not to have the power I was accustomed to.
