FiTech EFI-4 600 HP Reviews

You're gonna have the same issues on both sides (FItech or Holley) Facebook has a group dedicated to both of them and I followed both for over a year before I made up my mind and I decided on FItech. There is a wealth of knowledge for both products out there as well.

The key is setting it up and installing properly. Also, not expecting it to fix an existing problem.

If I could do it all over again, I'd go with a Edelbrock proflo. Mainly because I like the idea of port injection.
