@ZincGT - In my experience compressor surge is usually caused by the throttle plate closing before the diverter valve or BOV opens causing boost pressure in the intercooler piping tract to back up into the turbo compressor, or more boost pressure in the intake manifold than the motor can ingest making boost pressure back up into the compressor housing. So wondering what Adam is seeing in your data logs since the factory DV is electronically controlled?I definitely need a BOV as I am getting some compressor surge now. I didnt reuse the vanes, just showed them in the stock tube.
I’m venting my factory DV to atmosphere and notice via the noise of the boost pressure venting that there is no lag when the throttle closes and the factory DV opening to vent. If your logs show boost pressure dropping at throttle close then I would suspect your CR performance turbo needs a ported compressor cover so the manifold vs compressor pressure differential can vent at WOT. From the links below it looks like there is not a CR Performance ported option, but the Precision Turbo upgrade for the Mustang 2.3 has one.

All this to say it looks like you may have maxed out the airflow of a stock head with stock valves and cams at 27lbs on that turbo if you are getting compressor surge with a properly functioning DV.
