Checked manifolds as well ?
Also, the o ring that seats in the throttle body to intake 90deg bend is hard to seat correctly, and the plastic of that bend piece (that holds the MAP) also fails there, leading to cracks thst open under boost, you lose pressure etc.
Replace the 90 deg intake part with genuine is the only option there.
