You're welcome!

I can't say if it's the best, but I went with AA because they're the most reputable name I know. I was looking for an equal amount of performance and peace of mind that my car would be running well.

Think maybe I'll do the PE and decide on the tune later. Maybe by then I'll have a local shop who can do it, which would make my decision to do it MUCH easier.

The process of mailing in your ECU to AA is painless, but getting it out is another story. I did as AA told me to do and ran into a dead end because they gave me the wrong information on two accounts (ECU removal and first startup). If you decide to remove it yourself, use the JB3 installation video on YouTube to help guide your way into the ECU box.

Otherwise, don't hesitate on the BMW PE -- you'll love it. I'd choose the BMW PE first, over the AA tune. When I first installed it, it was my absolute favorite mod, but my favorite mod was replaced by the secondary cat delete that I did to my BMW PE, which brought out and heightened the beautiful tone it emits.
