Here's the scenario (just went for a quick spin to verify). . .I'm getting on the freeway and have it WOT in 4th gear (I have a 5 speed). The boost climbs steadily till it hits around 13 psi - EGTs are around 950-1000 at this point. Instantly the boost drops to zero and the engine acts like it just quits. Also, the EGTs climb pretty quickly to 1250 so I back off the throttle. I can repeat this over and over. I can't tell how much I'm smoking at this point and if I am, it's not excessive. I would rather it not smoke at all though but it is a diesel
