I think Fi-Tech early on, like many new things that hit the market, had their bugs to work out but that was years ago. I haven't seen many complaints in more recent times.
Similar deal with Holley. Probably the largest used EFI in all of motorsports. Snipers being Holley's low cost entry level deal similar to Fi-Tech. Snipers have had some issues but overall like Fi-Tech, it's a very small percentage. As JLmounce eluded to, most can be linked directly to the car or the install itself.
We've been running 2 Sniper Stealths for more than 3 years and neither of them have had any issue at all.
Never heard of Ace till now. New player I guess?? I've only had direct experience with Holley and FAST.
