Symptoms like that could be caused by a bit of leakage from a split hose
(e.g., Michelin Man?) or just a loose clamp. How old is the Michelin Man?
Failure if intercooler o-ring, turbo-to-IC hose...? When the WGFV goes bad
I believe it typically just defaults to a 1.3 or 1.4 bar boost without
sudden cut-out (or at least that's what mine did).
