I have said it once and I have said it again, anyone interested in going faster and having more fun (better throttle response) in a N52 should get the AA tune.
The only reason I would say not to get it is if you live in an area where you can only get low grade fuel (lower than 91 octane). The AA tune prevents you from "getting around" in crappier fuel as it is more tuned to higher octane fuels. The stock engine can modify the cam settings to run (albeit less power) on lower grade fuels.

Just trying to make a comparison as to what everyone would rather spend their money on.
I always run 93 octane, I have tried "plus" which was 89, but I like the way my car feels on 93 much better.
I wonder if the difference in the AA tune vs stock is similar to stock with 93 octane vs stock with 87 regular (when the car "detunes")?
