I have come up with some graphs comparing an Auto vs. manual GT. These are meant to be informative and not a slam at either. I used the time slip posted today by elvism in this thread as an example of a good running auto (13.50 ET) with a tune. I compared it against three runs from my manual (13.66 ET. 13.46 ET and 13.38 ET). The first run is before I got my tune, while the last two are after my tune was installed. The graphs show the time differences between the two vehicles at the clock points alone the track.
I was impressed by the consistency of the shape of the three comparisons and I believe it points out the strong points and the weak points of both the auto and manual. The first 60 foot shows the effects of the driver and as such, it shows no advantage to either car. Immediately after the first 60, it really shows the strength of the manual. I believe that advantage is caused by the manuals lower 1st gear coupled with the manuals lower rear end ratio.
But in every case, starting from the time the manual has to shift out of first gear, the auto really comes on strong. If the manual was leading, then the auto cut down the manual's lead. If the auto was leading, then it increased its lead. This really shows the effect of the tightly spaced 1-2-3 gears in the auto vs. the wide 1-2-3 gear splits of the manual.
The top end is where the auto's wide 3-4 gear split really hurts its performance. In every case, the manual was accelerating harder than the auto after the 1,000 foot mark which coincides with the auto going into 4th gear.
Again, I though this was an interesting graphic and not meant to prove one was better than the other. I hope you will find it interesting.

Pretty factual! That's a good explanation of the differences 
It's actually seen in the first video I saw of the GT and a GTO at the strip. The GT handily beats the GTO through the first 3 gears, and loses momentum in 4th where the GTO slides right by.
