I've used both also, with and with out a cam. I beta tested for SC when they first released 07 support, I'm beta testing the new trans functions now. I was the fourth person to receive a dsp after their release. My opinion is that their stock tunes are pretty much identical to sc. At the track dsp canned tunes consistently underperform sc. For custom tuning it's obviously a different story. That's why my recommendation is sc for mostly stock vehicles and dsp for cammed vehicles.

But that's just my opinion.

 

good feedback frog. could be a difference in pcms (old 3rd gen vs. new 3rd gen). i know for certain my truck liked the dsp more though (canned 93 vs canned 91). Its also possible the pcm reset just before the switch could have had a strong impact on it as well.
