Please see thread "All You Lowly 328i Drivers". I've talked to Travis and a gent called Matt. Obviously your car is the one they referred to as "coming in next week". Unfortunately I'm in NC and will have to do the download myself which both Matt and Travis say is easy. Matt just told me yesterday they will tune the download to your particular car, modifications like exhaust, intake and fuel grade burned. Both said increases vary but stand by 22-26 HP and about the same torque increase at the rear wheels. For the money that is a nice gain. Holding my breath to see your before and after numbers. Also, please kinda watch them, if you would, and give your opinion on a non tech doing the install.
