I don't know of anyone that is on here that is running single shots with PHP or DP tunes right now. There might be somebody out there lurking but not that I know of. I am running PHP tunes but on stock sticks.
Might be able to help you with this
Not sure when you're thinking of getting these but i just got my 250cc single shots that are going into my '53. Wont be putting them in till later this winter and im still unsure what i wanna do for tuning but im thinking DP again.
Might be comparing apples to oranges with how my truck will be set up though
