I have an '04 Limited Platinum Series and I added Stage 1 when the car had 2000 miles on it. It now has 28,000 and has made countless trips down the dragstrip (best time of 14.4 @ 95mph) and it's driven fairly hard on the street too. Not a hint of trouble out of the tranny, although I did my dealer do a full flush and filter change at 24,000 miles, which is earlier than recommended. When I'm driving in town and know my speed won't be exceeding 55mph I keep the gear selector down in 3, not D. I don't kick it into D until I'm on the freeway.
There is a lot of discussion on various PT forums about how the auto tranny WILL fail in these cars, and it simply is not true - they don't ALL fail. Yes, the failure rate is higher than average, but as a percentage of total auto PTs on the road the number is low. Without a doubt though, it's the overdrive that gets eaten by too much boost, so things like boost controllers are probably not a good idea as they are prone to part throttle overboost, and that is not good for the tranny. And in case you aren't aware, there is only one autotranny across the entire PT range, from Base to GT. The only difference is the Autostick programming used only in the GT. The tranny internals are the same.
I think that adding Stage 1 was the best thing I've done to my car and could never go back to factory stock Turbo Lite status.
