FiTech EFI-4 600 HP Reviews

I'm pretty sure I am going to go with a Sniper - either that or stick with a carb. Probably something like 90% or more of users find that none of these systems is perfect on initial installation. Even the Sniper is not without its challenges. But from what I have seen, Holley has excellent support after the sale, and a growing base of knowledgeable users that have seen and solved most common problems, and can point you in the right troubleshooting direction. Case in point, @AndyF who is active here on FABO can also be found participating in the Holley Sniper support forums at Sniper EFI and he is a wealth of information on these systems.
