Your boost gauge is wrong then...Is an electronic gauge or mechanical? You should find a mechanical and verify.. I dont trust the electronic ones at all.

With a stock lower, 3" upper, 9:1 compression, you should be seeing 17-18 psi of boost. The fact you are running 17 degrees of timing implies 18 psi as thats a safe timing for that boost level.
