Re: Holley Sniper installation video - 67 Camaro
The Sniper is a response to FiTech. Both are self-learned (but can be fine tuned). I looked into them extensively but never pulled the trigger before selling my 68.
FiTech does have something different, though, in their fuel sending unit. It's a small tank that your mechanical pump fills and has a high pressure pump inside to feed the EFI system. It still requires a return to the gas tank, however so it's probably easier and cheaper to just get a proper tank with submersible pump inside that is already set up for EFI.
All in you're around $1200 for the FiTech with the gas tank and pump for a 400 hp system. Add $200 or so for the 600 hp system.
The Sniper, I believe, is a couple dollars more but Holley isn't a new company and certainly isn't going anywhere any time soon.
both systems really made EFI affordable and both seem to work extremely well from the hype online.
