[s-cars] hesitation problem

[Calvin & Diana Craig]

Sounds like a bypass valve to me.  14 psi is definitely low for a max. boost
that you ever see.

not sure.  whenever i go from vacuum to boost pressure, i have a slight
(almost 1 second) pause/hesitation before receiving boost.  Also, when i am
accelerating in boost and change gears, the same problem occurs instantly as
i engage the next gear, it feels almost like a momentary jolt/lag (even at
only 5 psi shifts).  My car is still stock, and I do see 14psi on my boost
gauge, but my dealer said he thinks it could still be a boost leak of some
sort.  At idle im getting 15 psi vacuum pressure, is that normal also?
hmm... any suggestions would be great.  mike 94 S4
