“Shown here is a Ford video which explains the functionality of the Twin Independent Variable Cam Timing (Ti-VCT) system on the Sigma.  Premier Power have invested in a lot of development work, removing the Ford engine management system and replacing it with a different system.  The Ford management system is locked and set up to run a standard Ford engine.  Our calibrations are mapped to take advantage of the cams, throttle bodies and other modifications we make to achieve the performance levels we produce.  Enjoy the video”
