I have an 07 335xi. JB4, BMS DCI, ETS FMIC, AR Design kittyless DP's, Meth, CDV Delete. I haven't been to the track with it. I run MAP3 all the time.

Quite a few customers running around with JB4s locally. But we prefer the Cobb Accessport, especially up here. Flash tunes have far less issues than piggybacks.
