Quin - I think Rick has it right. See if that works. If not, (and this is the last alternative I would do), you could always try a custom burnt chip with dyno session. This is definately not the cheapest way to go, but if you have your Stang setup the way you want it and don't plan on making any more serious mods for a while, then this may be the way to go. Plus you will probably pick up some HP and TQ and get a great idle too!
Let us know how it goes.
