boost gauge reads 0.1

[Suffolk GameServer LAN]

I posted this exact question months ago to no real avail.
What I did find later on...............
The Michelin Man hose had a crack in the bottom.  Not big.  From the intake
manifold to the intercooler in the grill area.  Super easy to get to.
I'd get 1.2 - 1.3 for the most part.  However, I think the deceleration (to
produce) 0.1 and 0.0 was the crack opening up and letting air into the
system.  (idle is generally 0.2)  Food for thought.]
