Can't edit, so....
Difference in shifting from my experience:
Tow tunes have a higher shift point between all gears. I think it's 5mph higher than stock.
DD I think has stock shift points
Performance is same as stock but it shift into of later, closer to 42.5/45.
The above mentioned is with easy driving. If your on it more, then the shifts vary depending on how hard your into it. Dd/perf will shift later if your really getting into it.
If I recall, dd/perf/race all feel pretty much the same power wise when driving miss daisy. It's when you get into it more or get on it when you feel the difference in power. Hope this makes sense.
