As for your other comments, If the dyno has more information than drum speed and the ignition readings it is getting from the sparkplug wire lead exactly where do you think it is getting this information from? (actually, to be fair, there are dynos which use software that is supposed to compenate, but most don't)
There are a lot of reasons why what you cite as happening with your car can happen, some of those reasons pertaining to the dyno, some pertaining to the car, and some to both and there is no way to cover them all here.

So, the answer is, you don't have the answer. Not being a smartass, so please don't take any offense. The truth is, and you said it above, there are too many variables in order for a dyno to be right. We all agree that a dyno is a tool to be used for a direct comparison mod for mod on a specific car.
I, however, take some umbrage to the fact that the new GT dyno is being spoken to as if it's the gospel. By some people who say that the numbers would be even higher in 5th, that car's 1:1 IIRC, yet will agree that in at least some cases a car will dyno higher in a lower/steeper gear then 1:1. Why not dyno the car in 5th and end the discussion? Same dyno, same car.
Also, no car is that efficient. Not one with tires on it anyway. So either it's a ringer, it's under-rated, or the car dyno'd higher in the lower gear. It's supposed to be SAE certified, so unless Ford changed the ratings, it's not 412. That leaves ringer and wrong gear. Which one do you think it is? Could also be the dyno and operator just suck. Which after reading some threads about the previous GT500 dyno there, I would agree with, or better put, wouldn't argue against.
Lastly, I'm glad Ford is making a worthy rival, both in v6 form and v8, to the Camaro. It is going to make the track a blast when they show up! It's about time Ford started dropping real powerplants in the basic Mustangs and GTs, and not just the Cobras and such.
