The software removes the top speed governor, enabling the cars to attain their ''natural'' top speed; and the V8 will pull right to red-line in top gear! Changes to the throttle mapping help soften throttle tip-in for a sportier feel and improved modulation capabilities. The combination of Dinan's re-calibration of ignition timing, fuel delivery, and cam timing produce a maximum gain of 9 hp @ 6000 rpm and 8 lb-ft @ 6000 RPM. Peak horsepower is increased from 414 to 421 at 7900 RPM.

Note: When ordering please ensure you have your VIN ready for the checkout process. It is crucial that it is typed in accurately and completely at that time.
