Think that's a great idea.
I know very little about Ford tuning yet, but did gain a reasonable amount of knowledge during my 12 years of GM pickup ownership. The GM LS1 derivatives *love* a good tune. And on the pickups at least, changing a few parameters with regard to shift points and eliminating stupid delays added to wait a few seconds before going open loop really seemed to wake it up.
On GMs, there were two types of tuners. The first type was the "handhelds" like Hypertech, Superchips, and Diablo, which simply let you load there "custom" tune. These were never highly regarded by the people who knew what they were doing. Everyone who wanted real performance did not use a handheld, they used computer-based software such as EFILive or HPTuners and then programmed their trucks using an OBD2<->USB interface. Alternatively, people would pay a tuner to use EFILive or HPTuners to custom tune their truck (sometimes even renting the hardware by mail). I've used both a Hypertech handheld and EFILive, and the difference was night and day. The big upside (and downside) to the computer software based tuners is that you spend time logging sensor data from the truck, adjusting the tune, and getting it perfect.
Additionally have looked at the mechanics of the tune Hypertech used on my GMC Sierra using EFILive....scary shit. For instance, the difference between their 87 and 91 tunes was simply to kick up the timing 2* in every single cell of the RPM*MAF high octane spark table. Additionally some of their tables were quite rough. I'm not a tuning expert, but this looked fishy to me.
Have yet to figure out what's good on the Ford side. I'd buy HPTuners in a minute if they supported 6.2s, but their stuff only works up to 08 5.4s. EFILIve doesn't do Ford. And I think SCTFlash only caters to tuning shops, not end users.
