AA stage I....whats your thoughts?

[Inspiredm3]

I have a buddy who is going turbo, and has the AA stage I kit on his car. I know it doesnt make major power, but compared to stock its alot better. I am looking into purchasing it, but would like to know what the veterans of FI think of it as a start. Any feedback is good feedback. thanks :redspot

Look into the Technique Tuning kit as well. If you are willing to wait, the twin screw supercharger might be an option, but there are no official dates of when the T/S will be available. Boost Logic, a new turbo company to the BMW world, also has a very nice kit for the money. AA stage I is reliable, but its far from being the best bang for the buck.
