I installed a FiTech FI unit on the Coronet during the resto. Been struggling with the system going on five years now. This winter I'm going back to a carb. In the five years that it's been on the road, the fuel pump in the Fuel Command Center died, requiring a flatbed tow; I then installed a Tanks Inc electric pump. The ECU in the TB died, fortunately I was coming up my driveway at the time. FiTech replaced the TB unit under warranty. About 6 months ago the hand held controller died and a "new and improved" controller costs $200. Through all this I still haven't been able to tune out a hot no-start issue.
If you go FI in general, and FiTech specifically, you're going to spend thousands of dollars and hundreds of man hours installing the devices and upgrading your fuel delivery and charging systems. You're going to join a half-dozen forums and scroll through hundreds of pages of threads learning how to tune your "plug and play" FI system. Or you could ditch the old carb, spend $400 on an AV2 and another $60 on a tuning kit and be done.
It depends on what you do with your car. If it's a DD, regularly driven in sub-freezing weather with radical elevation changes, then it might be worth it to go FI. But if its a 2nd or 3rd car driven a couple thousand miles a year around town...
