I was just informed by the shop that the Crossfire can't be dyno tested as there is a speed sensor in the front that works with the ECU to compare speed between the front and rear wheels. At 4,500 RPM the car shuts down as there is no wheel speed in the front while the rears are turning. No data available. There are a few lessons here...the first is beware the claims of the speed and horsepower equipment manufacturers, with no dyno information...how good are their claims? Secondly, ask around and test, test, test in your own car. Share what you find. Still glad to be driving a Crossfire.
