[335xidave]

I have to agree, get the 335xi badge off, and put the 3 at the end of Dinan. I did almost the same thing to mine, Dinan stage 2 ECU, Dinan Stage 2 Suspension, Dinan exhaust, and foot pedals. I drove mine, then an M3, not much difference. I live in Denver, the altitude effects the M3 engine more than the 335's. Also if you watch the Dinan 335 v M3 video on youtube, it opens your eyes.
