I think the short version on that is quality control.

To me, it seems like they got a bit too large too fast and simply scaled production. It takes a lot of effort to mass produce something with any quality. Even a blind squirrel might find a nut.

There are also questionable components within them, the first thing anyone experienced with FiTech will tell you to do is throw away the provided coolant temp sensor. It's inaccurate and can't be trusted....it's also one of the simplest components in the entire system, it's a stinkin' thermistor. A "quality" replacement is about $9 at retail pricing. To me, if they cheap out on that, what else did they cheap out on? Low end injectors? O-rings? Internal electronics? Oxygen sensors?


That said, I have installed one for a family member and it's been running excellent for a few thousand miles now. I would probably use one on one of my own vehicles, but I would for sure buy brand new and ensure I had a warranty of some sort. In the same breath, I'd be tempted to try a Holley Sniper kit...
