1.6 bar overboost on MC-2?

[auditude at cox.net]

Yes, over"spin" (the turbo) possibly/probably, but not overboost.

Michelin Man hose will not cause overboost, but the opposite, low boost or
no boost.

Most common overboost cause I think is the lower wastegate hose.   Don't
crack your wastegate open until you have verified.   You can test the
wastegate operation with a mityvac (or by mouth if you don't have one).
 Apply suction on the upper hose, pressure on the lower.
