I received my Moates chip in on Friday, uploaded my program and installed it yesterday. Haven't changed much, my main reason was to tell the EEC about the 4R70W gears in the tranny. Of course, much more is now possible.

I'm sure I'll be tweaking the shift points on the tranny before too long.
If anyone's curious, the chip is programmed with:
Base U4P0 tune
4R70W gearset
No shifting into Overdrive at WOT (from

Fan turns on earlier (from
here)
I have a question I hope someone can answer. My GT has a W4H0 computer in it. I've read in several places that the U4P0 tune is the best out of the auto tranny tunes. Anyone know the difference between the W4H0 and the U4P0? I'm not talking specific settings, just an overall summary I guess.
