^^^ If you are talking about s15 turbo's after about 13 -15 psi is pretty much efficiency range, anything over is minimal and hurting the turbo period.
On a gt2871R, I have definitely measureable different when settings are changed. Its your tune if it doesn't change. Contact steveshadows and I promise you at 17psi you will shit in your pants.
