I've had both.
Both of them shifted at 6000 RPM and turned on the cooling fans early as well as when the car is shutoff. Both gave me some kind of gain.
But like said above, the DHP gave me stronger upper end power and it pulls harder at higher speeds. I was getting lots of KR from the Intense PCM from high timing too. The DHP probably got rid of some of that KR.
Overall though the car feels slightly more aggressive and quicker with the DHP.

There are a number of Bonnies running them. ChadV has one too.
