[s-cars] air leak....poor performance

[chris chambers]

Bill,

had the same problem last year, it was the turbo outlet hose, clamp was
loose and caused a definite noise and loss of power. But yours could be
a different hose.

Looking visually won't work, build a boost tester and listen for that
leak!
