[s-cars] Hmmm, interesting problem.

[Pasqualoni, James E]

It is a different waste gate frequency valve.  It helps the solenoid controlling the waste gate cycle faster so the buildup of boost is more linear.  Not sure who carries them these days.  I bought mine from TJM Motorsports a few years back.

OK, you got me - what's a K-WGFV?  And how much?  And where?

:)

Thanks for the info,
