The 1987 GT was the only one from 1987-1992 that was rated at all. The ratings were carried over at 225hp year after year. In 1993 the engine was re-rated at 205hp. Although Ford stated the reason for the lower rating was because of a different method, the truth is it was just plain down on power vs the 1987-1988 non CA cars. They made camshaft revisions, computer changes, added Mass Airflow, a change in catalitic converters, and some other minor revisions. The 93's seemed to have the weakest computers, but in reality the 1989-1992 doubtfully had the full 225. By your logic I could just say the 94-95 GT's were overrated, since they had more in common with the 93's than the 1987-1992 cars. Hypereutic cast pistons replaced forged pistons in the 1993 model year for emissions issues. New computers were added to the SN95 cars, and a modified intake was added as well.

As previously mentioned you will need to get the rev limiter out of the way, they are set around 5500 on the AOD-E cars....As far as gears go, get the 3.73's, unless you plan to run a tall tire at the track. You will run out of gear on the big end with the 4.10's and a 26 inch tire.

Although the EEC-V computers have been found to be somewhat finicky when it comes to camshaft swaps, there are plenty of people picking up lots of power with the stock cam, ported heads, and a good intake. The "fuel management system" that powers some of these cars into the 12's is an adjustable fuel pressure regulator.
Killercanary had his SN95 GT running 2 seconds faster than stock with the stock computer and no FMU. I would say that's a pretty significant gain. Course, then again, maybe all SN95 GT verts trap close to or over 105 mph with the stock computer. (5spd)
At 5500rpms the AOD would be cranking down the 1/4 mile at 102mph in 3rd gear with stock sized rubber. I don't know of too many that will run 102mph near stock. I have to admit I don't know where the rev limiter kicks in, but you can always buy a tuner for that problem. I see no need for an FMU.
