[s-cars] Bosch bypass blowup

The TurboXS valves are adjustable internally via shims. A simpler solution is
the TurboSmart valve which is adjustable externally. Although others on the
list have insisted that an adjustable valve is not necessary, I have found
them to be required for precise tuning of the bypass function(no wise cracks
please;-)). I recently pulled 2 of my shims from my TurboXS valve to enhance
my turbo spool between shifts and found instead that I had encountered, once
again, the upper boost surging from the bypass valve. I reinstalled the 2
shims and the problem disappeared. I am planning to do some replumbing of my
I/C intake system with larger hoses and I will replace the TurboXS with the
TurboSmart valve. HTH.
