My Ride: 2008 535i LCI with sports/premium package, Sports trans with paddle shifters, CF emblems, JB4 Software, Dinan Exhaust, Navigation, M5Tech body kit, Carbon wrap interrior trim and CIC Controller.
I just installed mine as well the other week. I can only say I should have done it much sooner. The power increase is wonderful! Do you live in SC ?
