Actually, 15.8 PSI is the target for 91, and 93 maps, though I guess it could vary by RPM. I bet that is a compressor issue, not an octane issue. doesn't the stock turbo drop off significantly above 16PSI at sea level?

On a bigger turbo, I would agree that you could run more boost on 93 than 91 and make better power than just bumping timing might. In this case, I bet most of it is timing bump though.

I guess we could get Eric to look at the maps since he has ST.

And I agree, with most of your omments, that is why I am running the 91 map.
