Fast xfi

[FordEvangelist]

Is anyone using a FAST XFI system on their street car? If so, what's the verdict on it?

Does it completely replace the oem computer?

Thanks.

Fast

It does replace the factory ecu. As far as it's ability it is a great system. When tuned properly the driveability is great. If you don't have a radical set-up I would stay with the factory ecu.
