Seems like this car would be a great candidate for a nice meth injection system like an Aquamist HFS3. With lower octane gas, less timing is safely possible and less boost is safely possible, resulting in less power. These cars have very high compression to begin with. You don't want to blow up your engine. They are not cheap. The meth injection would help provide octane consistency.

The dyno result means more if we know what kind of dyno it is and whether the number is uncorrected, STD corrected or SAE corrected.

Could be belt slip, could be air leak. What is the observed peak boost? What are the observed AFR?

I am sure AA will help you figure it out if you can provide them with some data. Logs of data from a good scan tool are ideal. Probably better than just a dyno sheet from a non loading dyno like a dynojet.
