Pinch off the wastegate hose and go for a rip. See if you cant make more boost. If you can't, thats all your truck has.

If your making the same boost as before there may be a wastegate issue. The linkage to the waste gate may not be adjusted tight enough, and is always open a little. It's a possibility.

Correct, boost is directly related to fuel. The difference between stock and my 65's was 7psi more boost.
