I went from a DP to PHP. Night and day difference. The PHP tunes are much more drivable. The throttle is smoother as are the shifts.
The new tunes feel more sophisticated and refined where as the tunes from dp felt like they were made for a high school kid with daddy's money (in retrospect).
However, I do say I like the DP shift strategies better. I am fighting a shift between 25 and 30 mph and might send it back to get fixed
