I can actually feel a bit of difference in the car surprisingly too, which I was not expecting, but as the car climbs in RPM I can tell it pulls smoother and harder. I attribute that to the engine being about to utilize the 93 octane fuel and timing a bit more. The GTS tune is very sharp and I can see why it's popular, but I honestly can't tell enough of a difference in it from stock. The one thing I will say that I absolutely have noticed is that it requires driving a tad differently than before. What I mean by that is I can tell the GTS software is expecting more torque at lower RPMs than the stock non-GTS S65 outputs. When driving in D4 previously on stock DCT tune, it shifted in a much more intelligent manner than what I've experienced with the GTS tune. I'm experiencing a bit more gear hunting and a fair amount more laziness to downshift when going uphill, or just rolling on the throttle a bit. It is most happy to drive more aggressive, and it definitely expects more low end torque.
Overall, I'm pleased enough with the two tunes. My favorite thing I got from Alex BY FAR is the Euro MDM coding. That option dramatically changed the driving characteristics and greatly improved the spirited driving for me. Also, I am definitely leaning more towards going to the cat delete stage 2 now. I am just going to have to find an exhaust set-up I'm pleased with because MPE is too loud for me right at the 75-80mph mark when in 7th gear cruising on the highway. It's great for eveything else, but the resonance/drone right at that speed is too much for extended trips.

Interesting feedback!
Loaded Alpines GTS sw the other day. Immediately noticed quite a bit more violent (manual) gear shifts, the yolting is much stronger compared with my original (European) sw. This is in S4 mode which I normally use.
The Eu sw doesn't have the reverse delay I read the US have so no difference. Shifts supposely 100ms vs 120ms (believe tuned down from GTS 80ms) which I can't tell the difference of really. I'll feel my way for a while, maybe go back to original Eu which is aggressive enough while not "disturbing" grip.
After some more driving with the engine tune its shining more and more. Initially thought it was the cold weather but it is really providing more grunt. Coming up above 150km/h it pulls stronger no doubt.
Edit: Driving a bit more in D I see what you mean, it drags its feet a it more before it shifts. Possibly another reason for me to go back to stock.
