Samco hose was RE: [s-cars] Miss & whoosh

[Michael Bess]

Found the problem (or at least one of the problems):  The turbo outlet hose
has a split in it. 

Now to replace:  Who has SAMCO's at the best price right now?

I have a similar problem... although not exactly the same.   At lower RPM, 
say from 2500-3200 I can hear a slight wooshing sound and sometimes I feel 
like there is overboost.    I also get poor gas mileage.

Question:  Would the engine run well most of the time if the pressure hose 
to the ECU was leaking or had come off?
