They are running hidden Holley EFi stuff to control timing and data log. Don't know if that alone makes them faster per-se but it does give them a better handle on their data with all the sensors. You can run whatever sensors you want with the Dominator modules - wheel sensors, driveshaft speed, etc. It all helps.

Over the summer I spoke directly with one of the more competitive F.A.S.T. racers about this idea and he basically admitted he was behind the curve without it.
