[USA-RET]

Title says it all. While there are plenty of tunes available from others, having a BMW sanctioned tune offered may appeal to some buyers.

I have the Dinan Elite and am quite happy w/ the performance (and the piggyback warranty offered). I also have a MINI w/ the factory JCW tune which is their version of the MPPK, and it transformed the car too. While the Mini tune was expensive compared to the Dinan on the BMW, having the newer performance exhaust was worth the extra IMO.
