Reaching out for some insight. Having issues with underboost…. checked all my charge pipes hot/cold side removed and reinstalled with new gaskets everything is tight and sealed I did a pressure test to 20psi. BOV is tight and secure I removed to inspect and it’s good. Boost Solenoid is brand new all vucuum lines are good. Only thing I’ve yet to do is to try adjusting my wastegate. Pure stage 2 turbo set wastegate before install.
