I happend to run across a cobra pcm that is from the same year and trans as mine. I was wandering what it would do if I swaped them out. I understand the fuel mapping is slightly different betwwen the two. My motor is stock exept for a cold air, full exhaust, and underdrives.
I wouldn't do it on a stock GT motor. If you put the cobra computer on with 24# injectors, you will likely see a drop in power since it'll be running richer. The cobra has better flowing heads and intake (and a different cam, but I might be wrong) to go along with the extra fuel, so you were to do a decent HCI swap, a cobra computer might be an option if the price is right.
