Yes I am at a loss to as to how to diagnose loss of fuel pressure under boost - unless a gauge is specifically set up for road test.
It really seems like a massive fuel dump on boost - or an air leak - or both.
The best way to test air leak is pressurise the system and find where it is leaking from - you may be surprised. What does the WP drop to on boost? You can test this in the w/shop. Presumably he has if he is checking the WUR out.
