got boost (slight return)?

Kind of off the top topic, but has anybody seen were the boost seems to be 
across the board my situation whereas at idle the dash readout 
used to read 0.3 to 0.4, now it usually reads 0.2, with boost on the high 
side only going up to 1.6 or so?  I've seen low boost at the top end before, 
but not with it reading lower at idle too.

Sounds like it could be caused by a pressure "burp" from split hose
or loose clamp. How is the Michelin Man hose condition?
