I installed a kit from our first Fitech shipment once we became a distributor and i've been very happy with it. Before this I had run the Edelbrock E Street which started out great on my Bronco, then later gave me nothing but problems. Second kit I ran was the MSD Atomic which was good, but took quite a bit of fine tuning on my end to get it fully dialed which was fine, but required extra time spent fine tuning, and a few calls to MSD Tech for advice. When we recieved the Fitech units in, I was able to sell my MSD Atomic for more than the Fitech (Extra Bronco Fund Money) and purchase the Fitech. This kit was easier to install than any other kit out i've ever used, runs better, and burns cleaner than the Atomic or E Street did for my truck. I had one issue 3 months into running the Fitech that caused it to run super rough at idle and almost die while driving home one night. I drove it to work the next day, and ran a dedicated 14 gauge ground wire from the throttle body to the neg terminal of the battery, reset the parameters and it's been good ever since. I've since driven it to, through and back from the Rubicon, drive it every weekend, take it camping, and it runs like a top. Recently I met a customer that came to Wild Horses that I was telling about the Fitech Kit, come to find out that he been running two Fitech units for the past 4 years on each of his trucks with no issues other than needing to add a dedicated ground wire (Which isn't in the instructions, but should be) I'm a believer in the Fitech EFI and won't be changing out, however we will be installing a Sniper on one of the rigs here in the near future, so we will be able to give some solid feedback on that kit as well.
