That is pretty close. Won't find a lot of horsepower either, but the potential to find more will be there. You can do individual fuel trim per cylinder, can also do sequential injection with some legal mods inside the Optispark. Will also let you change injector vs. intake valve timing........ Datalogging is built-in and is far better than most other EFI systems, only a Racepak would be better but is not needed.

FAST XFI has all that. I have worked a lot with both. Most of the fast Super Stock LT1s are using FAST.
