Also, I believe pushing the stock turbo to that level may be putting a lot of strain on the compressor. I'd love to see the compressor maps for the stock snail.

I am pulling all of the relevant logs I can on my next run on their recommendation, using the Torque app and sending the results to AA for review.
Looking at:
AFR - commanded
AFR- measured
Engine load absolute
Engine RPM
Fuel Rail pressure
intake air temps
MAF rate
timing advance
Turbo boost & vacuum
