The F.A.S.T. products are for crate engines, for now anyways.

top notch company but ya I dont think they make any products for anything but crate motors. Not sure how much modification this would take to fit on the GC

A speed density based aftermarket engine management system. How much depends on what level you go with; anywhere from $1500-3000. There are quite a few Mustangs running them with good results. I also hear good things about Big Stuff III.

I have two FAST systems, one in a supercharged 95 mustang and the other in a turbo cobra replica. I am pleased with performance from both. there is a down side to mine however and i'm not sure if later versions correct the situation. it seems when i light em up through the gears and then let 'off' the system doesn't read the fuel map during decelaration and i get popping through the exhaust systems. it doesn't load the engine up it's just annoying especially in the open cabin of the cobra. i have heard that the original designer for the FAST system is involved with the BIG STUFF and the aforementioned issue has been corrected.

You could put one in the GC but you would also need a stand alone system like Powertrain Control Solutions to manage your transmission. I know someone with a twin turbo GC that installed the FAST and it would not shift out of first. I told him about the PCS and then he found the week link in his motor at 14psi, lol.
