Hi Loesch
Are you still a few psi short up top - like me? I have been trying to trouble shoot a dozen times over the last 6months, but no success so far.
I am comparing my lack of boost to this log from Peter...I am starting to think that his log was just run in at colder temperatures - hence the turbo can make more boost. The F-series turbo inlet is different so I deviced a leak tester myself from a plumbing cap
