I had installed the 600HP system the 1st year they came out. Several issues with locking pins on cannon plug connectors failed (pushed back pins, hunting IAC adjustments (would not stay put), random dying like the system had a OFF command and no codes (always started right back up), a couple of shipments back to FiTech for repairs. The random dying continued so even though I had everything wired with aircraft quality environmental splices and connectors. I went back and soldered every connection (thinking dying with no code = loss of connection) and had one more engine shutdown at low speed in a traffic circle.
That was enough for me, and I went back to carb.

I know that Jay's shop at Vintage Motorsport had started using the FiTech and quickly moved over to the Sniper systems and still use them.
(Sorry Jay for speaking for you, but I do watch your delivery and dyno sessions on youtube, lol)

I ran one for a hand full of years and would say I’m 50/50 on it. First, they are a hard parts company, not a tuning company. It took a while to get the tune really good. Don’t believe the “tune themselves” if you have a fairly radical engine. Once your in the ballpark though, that works well. I don’t believe the Sniper is substantially better (or worse). They source their parts from Oem just like fitech. They are a bigger company with more units out there and thus more support from them and independent forums.
Installation is everything. I had no problems with electrical stuff. I would still be running it except for a injector failure the day before a big trip. Pulled it off, threw my old carb back on, and went. Guess I’m too lazy to go back.
A few suggestions if you decide to go with either system.
Do a good job on the electrical. Shield wires if there is anything that could cause interference.
Don’t mess around with in-line fuel pumps or surge tanks. Put a good in-tank pump in. It’ll be a cleaner and better installation.
O2 sensor failures are possible with either system. Once you get the tune where you want it, turning the self tune off will keep it from going crazy rich or lean if o2 failure happens or you develope an exhaust leak.

Good luck if you go this direction. I actually enjoyed the learning to tune part and may get mine back out now that I’ve talked about it so much.
