I looked at the Mega Squirt. It looked way to do it yourself for me (I'm not going to solder my own boards). However the software looked to be decent to me. If you have it together and running decent (tuning issues only), you may want to see what you can do tuning it yourself. If you have a decent wide band O2 and the software to data log, give it a shot.

Another option is to rent dyno time to tune yourself. I have talked to a couple shops that will let you use a good wide band and operate the dyno for you for $100/hour. You just have to do the tuning yourself.

You might pick up a EEC IV Ford ECU and connect it up. There are several good shops here in Ohio that will chip it and dyno tune it. The 88 and older 5.0 mustang was speed density and 89-93 are massflow. I would guess you could get one at a salvage yard for a few hundred bucks.

Your going to spend big dollars changing fuel pumps and maybe lines. Then the intake and carb. Pile an ignition set up on that. A lot of wiring. Then you still have to tune all of that stuff and fix all the problems that pop up on a carb, which can be a pain too.

PS
If you have a cut up wiring harnes for the Mega Squirt and decide to go to the Ford EEC IV get the wire harness too. I think some of Mega Squirts problems is electrical noise from all the cut up, soldered up, wires.
