Boy,   you sure do like to respond. First of all, my custom software is set
at 28psi+. The Apexi regulates this back to 22/26psi. I do not use the WGFV
because of WG creep. Although I run the Pederhousen Big MAF I still get the
MAF cut when I exceed parameters. These are not stock parameters!

Secondly, the boost surge I have experienced, is also being experienced by
all the big turbo users that Mike Pederson and I have talked to. Yes, these
include the Innovative turbo users also. More than a turbine section problem
the suspect now is the intake manifold and throttle body. We have a
significant pressure delta on either side of the throttle body. This delta is
enhanced whenever you lift the throttle while on boost. It is further
enhanced when the turbo is under load(as in climbing an incline). My everyday
drive has me climbing I-70 from Denver to Evergreen at over 8000ft. My boost
surge can be severe under these conditions.

I have another possible fix under development and I'll report back when I
have data.
