Felt it was worth mentioning this since I've had this on the car for a few weeks now and I'm impressed.
My car is stage 2+ and I've realized that running standard software was preventing me from getting the most from the car in terms driving in a normal fashion around town etc in 'D'.
After my tuning was completed I had noticed the subtle shift in where the torque band started, not really a major problem but evident. Anyhow, since mapping the gearbox it feels distinctly like the gearbox 'fits' the engine better. By that I mean that the box now stays in a higher gear for a little longer, not excessively so but enough to keep a little more torque available when in 'D'. It is also more ready to change down 1 gear when accelerating from typically urban speed limits without giving it a heavy prod on the gas.
By way of a comparison imagine a manual box feeling like it has a poorly chosen set of ratios.
As for manual via paddles and 'S' it's better there too. All of the benefits that Revo publish are there and they make a positive difference.
All in all a series of small changes that amount to a substantially improved driving experience.
