Does anyone have any experience with chip tuning? I am thinking of doing this with my c230k and wondered if anyone might have any thoughts or input. (ie. harm to engine or transmission, etc) I am looking into Wetterauer's tuning products. Any comments would be appreciated.

More boost is harder on the motor but yields more power. Since your motor is designed for forced induction adding a bit more boost at the right times will not likely compromise its longterm longevity appreciably.

Hope this helps...Lee
