I have a 91 20v quattro and have been experiencing a couple problems.The ma=
in one has to do with the turbo boost pressure going up to a peak of about =
18psi and as it peaks it will then drop of and occilate back between about =
13 and 18 psi. You notice a surging of acceleration along the way.Also rece=
ntly it has been stalling when you let off the throttle after reving it at =
high rpm. To keep from stalling you have to get on the gas and ease it back=
 to idle. Any info would appreciate much.  Steve Holbrook
