JordanL91 had one on his truck that burnt down.

I don't think it had anything to do with the quality of the kit, just one of those things.
Curious myself about the aftermarket kits. Given the widespread availability of Ford OEM stuff and the reasonable cost, I don't see myself going aftermarket. Can't really see any performance or tuning advantage either.

I too would like some input from someone that has used one of the aftermarket kits. I seen on an episode of roadkill they put a fuel injection setup on a 55 Chevy with a 500+ cubic inch hemi (yes they put a hemi in a 55 Chevy) and they tuned it and got 17 mpg on the hwy

My father has a Holley Pro-Jection TBI system on an early 70s Bronco with a 302, the PO had installed it.
Once all the bugs are worked out, it's a great system; it starts just like any other EFI system (no pumping of the pedal) and the engine operates well no matter if it's down in the lower elevations of the city (5,300') or up at 10 or 11,000' in the mountains.
But ya gotta get the bugs worked out; in his case, he kept burning out fuel pumps... Holley covered everything under warranty and had a local shop do all the work (and even flew a factory rep out for a few days), something about apparently too much restriction in the fuel lines was causing the things to overheat and burn out.
But it's been functioning very well now for more than 10 years and he's happy with it.

How much tuning does it allow you to do? I'd like to have the mpfi kit but dang it's high and would cost more than my truck is worth lol.

I'd like MPI, but I'm not sure I'm gung ho for throttle-body injection. Having said that, there are advantages, both in tuneability and consistency for even the throttle-body injection.
As an example, I'm looking at used boats right now, and have found that Mercruiser's 5.0L in 2bbl carb'd form puts out 220 HP. In throttle-body form it puts out 240. And in MPI form it is 260. However, I'm betting that there are compression ratio differences, although I haven't proven that yet. In any event, properly set up with a good engine management computer there is more to be had with injection than with carbs.

Fuel Air Spark Technology (F.A.S.T.) has an EZ EFI kit I was thinking about buying, but i'm going to 'upgrade' to a 92-96 F250 factory fuel injection system instead.

From what I've read, everyone seems to have great luck with them, just have to install a sensor or two, but then you're all set to go. They're around the same price as others too, this one can be ordered with a tuner as well so you can infinitely tune it to your preference.

The Edelbrock system retails at $2500..Has a stand alone high pressure pump system that installs in the engine compartment. It is pre- set for the application..and comes with a wireless tablet for final tune. I was impressed..

I will have to check out the fast systems. They are supposed to be really good setups. I can't justify putting a setup like that on my ol f350 but if I found a truck nice enough I would consider it
