I have a local guy that does BMWs, MB SLKs, Audis, etc. that says if the Crossfire uses the same Bousch ECU that's in the SLK he can chip and tune mine for $400.00. He told me that I can expect 15 - 20% increase in hp and torque.

I'm giving it very serious concideration. The next autocross is May 9th. If I'm going to do it I will get it done before then.
