less than 300 for the computer (one to build, if you can solder and follow directions, its brainless)
This is who I got mine from and there customer service has been amazing! I even have thier fuel injection book (great for learning about any kind of FI system)
Megasquirt Kits / Assembled Engine Management Systems, Wideband o2 Sensor Systems and tuning products - DIYAutoTune.com
and yeah, MS is SD.

I think a lot of people look at the MAF swap and ditch the idea b/c it looks so complicated on the computer screen. Things you have to do like rewire your harness to get rid of the batch fired injectors and wire in new injector wires for sequential EFI and move around several wires in the EEC connector, but it's really not that difficult. MAF will do everything your wanting w/ a tune and will also run smoother and possibly stronger than the carb will.
Like said above, the stock 19lb injectors may not support 400hp, but 24lb injectors should support that no problem. The stock 5.0 truck intake shouldn't have a problem with 400hp. It flows pretty good air.
Here is a color coded chart for which injector wires need to be moved, and where your moving them along with the injector wires your adding in for an MAF swap. http://farm5.static.flickr.com/4017/...d936b8da_o.jpg

So this might be a dumb question but can you rewire the injectors to get rid of the bank firing injection but still keep SD? it seems to me that would give you better milege thats really all i want ive got enough power but when i tow something heavy my milege hits the toilet and i bet some of that comes from the bank firing injectors

OK bud that makes sense so i have the 5.8 and the E40D so i need to get a stand alone trans controller or a C6 haha and a new computer from a mustang or a lightning first gen and then i have to have it mapped and then i need a MAF sensor? thats probably gonna cost more than the whole truck did and for what, 5 more mpg and the possibility of more power so i can blow up my E40D haha its not really worth the trouble is it ?

You'll have to get a TwEECer unit, or something of the like...Mustangs didn't come with 351w....So a A9L 302 computer won't work...
And technically, given fluid and filters have been changed somewhat regular...that E4OD will last very well.....COuld always use a shift kit....
Also, as to the MAF sensor, etc....If you simply get the TwEECer unit, etc...you won't need MAF....
But if you DO go ahead with the swap....Find a late 95/96 model truck to yank the ENTIRE wiring harness, injectors, computer, etc from..
But simply enough a SD computer editor will suit your needs....

the MSIII is sequential, and SD
im practiacally becoming a salesman!
oh yeah, and they have an add-on tranny controller
however at that point you would be better off with a newer ford computer and a tweecer like sidewinder suggested. although sequential would do more for drivability and emissions. i have heard before that it is only good for about 1/2mpg over batch. wideband control would be more beneficial.

No.. but a stock 4bbl carb and intake won't either so it's a wash in terms of cost.

Nope, that's physics and there is nothing you can do about it, a heavier load takes more energy(i.e. fuel) to move. No vehicle gets good fuel milage when towing not even the new trucks.

The reason I said it would work, is because you yourself have mentioned that the stock Intakes, etc flow just as well, etc as the high $$$ ones....Albeit a nice P & P style work couldn't hurt it...lol

You can't lump all the stock intakes together and make that comment however, the 5.0 truck and Explorer intakes are big enough to support better heads and more displacement and have additional potential with porting, but the 5.8 truck intake isn't nearly as good and the HO is too small for anything except a 5.0 with stock heads.

I just remembered you saying the factory 5.0 truck intake flowed pretty much as well as a aftermarket one.....To spend the money for other things...
