I have been corresponding with Matt (BMW Power Consultant) from Powerchip about a possible group buy/discount. Just wanted to send this out to see what kind of interest there is before I call him with specifics. If you want info the link is:

I will probably call him on wed or thurs to let him know what kind of interest there is. Let me know if you are interested so that I can give him some kind of numbers.
