The EFI myth

I have to agree with this, I too almost went the FI route, but something held me back. These aftermarket kits have not been refined like OEM stuff. Now, I will say, the conversions I have seen done do run very well, efficiency and performance are great. For me, as others have said, it is that nagging wonder in the back of my head, wondering when is it going to fail. I take several trips a year in the Dart, through a mountain area where for 2 hrs there is no phone service, sure enough, this is where it would fail.
This is the exact reason I have my MSD E-curve setup for sale, brand new. I have heard a few reliability issues with the boards in them. Again, the aftermarket doesn't seem to have electronics scienced out like OEM.
On my road trips, I carry a spare ignition module, voltage regulator, belt, electric impact, plugs, ballast resistor, etc. That way if something goes wrong, I at least have a fighting chance at getting myself going.

The OEM has thousands of hours of reliability testing behind them. Aftermarket does not have the resources to do much of anything.
