Factory efi
Might take a crack at racing a Ford 4.6 in stock . Do I keep the factory EFI set up or is there an aftermarket unit? Change out the computer from the factory unit with what? I've seen the set ups with the FS cars and I don't think I can use this stuff.

Nothing wrong with it..Lot of good ODB2 tunes to make it run. In fact run as light as a P/SA car...give Mike E in his Caprice a tough run. If you build it..want a heads up run against my Pure Stocker ;-) Bet you a whole $1 and dinner.. |

Re: Factory efi
I have tuned several with both FAST XFI & Holley. I would certainly disagree. I can & do make the FAST system do things the Holley can not. Besides the Holley ECU failures I have seen.

Re: Factory efi
While I only have 1 jeep running the Fast XFI2, I am quite happy with it. Bought used on EBAY - (replacing the obsolete silver FAST - no longer supported). It is still a work in progress - not a lot of Jeep 4.0 support (on anything!) but no tech problems at all over 2 years.
