I wouldn't touch the Speedmaster unless the customer forced me LOL I have used their throttle body system, and although the program is much more comprehensive than you'd think, if you think support sucked with FITech, you'll go through upload and patch hell with them and in the end will likely just have to do some guessing.
I have the Edelbrock kit for my F100 right now, Brent was the only one who could get his hands on one for me and as always, treated my right. Remember though, you get what you pay for with EFI. My Mustang runs a 5000 dollar setup with an additional 1000 or so in in-tank sump and aftermarket rider chip to allow "real" programming. It runs like a modern car because it is set up like one. This should be pretty slick, but I don't expect it to be anything like that. Haven't got it running yet, but it's a pretty good deal for parts alone, some things so far.
- Injectors are a bit small for anything above 500 HP, the 600+ HP rating assumes you swap to a 42 lb injector
- Doesn't come with fuel pump or regulator and will require a return system, I think you used one of those sumps before, IMHO, avoid those, set it up right with a nice return system and avoid the chance of a needle and seat failing and a sump/tank underhood
- If you want to run a heater, the EFI and the stock water temp gauge, you need at add a bung, I welded one in, some recent posts here about adding them elsewhere
- The intake needs to be ported, it'll run, but the ports look like they aren't finished at the head side, surface is OK, but they don't match anything in shapeand no two are the same to each other. I worked mine as much as I could without increasing volume too much
- Brent got me the the kit with the tablet for bluetooth programming, you can order without for about 100 bucks less and use an Android tablet you have, but I figured for 100 bucks, why not
- Be conservative on the cam, the intake isn't meant for low end, so if you want it to behave nicely, it needs to make vacuum. FYI, I am running a 230/236 hydraulic flat tappet 112 LSA with a 461 with ported heads, if my heads were better, I'd likely run less in my truck
Other than that, it looks good. Not sure when I will have it running. Just finished up the 461 for the truck and on the fence with a decision on selling the 461 after the dyno because the current 390 runs so nice and putting the EFI on it, or just do the EFI and 461 swap all at once in the truck. (It's easy to be lazy when both toys are running well LOL)
Here is a pic of original mockup, it is pretty, and like I said, the price is pretty good.
