Questions for you

1. What companies are currently doing tunes for the N54, and the N55?
2. What is the best tune? (I know, loaded question)
3. Is the BMW Performance Tune, currently available for the N54, not the N55 really a cost effective option?
BMW Performance Power Kit (For Vehicles with M Bumper) $1,861.98 on the BMW Website
4. What are the differences in performance, sound, and cost for the different kinds of exhaust (axle back, turbo back, etc...)?

if you would like to dismiss this that's fine, but I have looked at this site enough to know these are common questions. It would be nice to make this a sticky and really get common questions/answers posted.

I do not envy the person that intends to keep this up to date
