Many resales of the Holley (Sniper) & other aftermarket Fuel Injection Systems

I have been using a FiTech system since they came out about 8 years ago. From what I have noticed, a LOT of people can't follow instructions when installing them. They blame the system and then post pics for help and everything is a rats nest of wires. The other issue I see a lot is people have a poor running engine and install EFI hoping it'll fix all of their issues and it doesn't. It still runs the same as before and they blame the system. In terms of FiTech, it is not just a bolt on and go unit, you need to set of basic parameters and set your timing correctly. It'll self learn to a degree, but if there is a big performance issue, you'll need to manually adjust a few settings to get it close and then the self learn will dial it in. The data logging feature is great, it'll show you how much adjustment it needs to make, if they are all maxed out, you need to change stuff manually. Mine has full adjust for low rpm fueling, I'm still working my way through it, when I adjust the fuel for low rpm, I get a bog when throttle position is rapidly increased. I don't blame the unit, I blame me for not knowing exactly what I am doing.
