Default Mechanical Gurus please help, having a low boost proplem.....

I have a 1997 1.8t with a APR chip, I used to get 15-17 psi constantly. My problem is I only get 12 max! Here's a list of what I've replaced or swapped, any ideas what else it could be?

ECU/chip
TB and IC hoses
3 BPV's
Turbo/Manifold/Cat and all gaskets
MAS
BFV
Crank case breather

TIA

Nope, everything was clear. I just don't get it.

Default Is it happening all the time now? You might need to log the 02's so you can see if

your running too rich. If you are this will cause the car to run low on power and not spool up the turbo enough.
