I own HPT Pro.
I've tuned with both HPT and DHP, however do not own DHP.
DHP is more sucumb to open sourcing the maps, I believe.
Not to mention you cannot force readiness monitors with the HPT, as you can with DHP.
I'm not familiar with the emission laws in Massachusetts, so I'm not sure on the strictness of your tests or even if you have a test.
Sounds like you have a pretty sweet build going.
Thanks, yeah nothing too serious though.. I'm piecing together an IC as of now, and that will probably be it until the stock 112k mile trans takes a dump.
