Went from the dsp 7137 and tried the superchips 3865....all I can say is wow!!...If you are just interested in a simple canned tune I highly recommend the 3865....now dont get me wrong I have nothing bad to say about the dsp..great product....had a bully dog triple gas and that was also a great product but not as good as the dsp....if you are looking to go deep into the motor with performance work then the dsp is the way to go but if you have simple bolt ons(intake, exhaust, ect) then the 3865 is the way to go....installed it yesterday and im already impressed, going to give it a couple more days but I might be selling my dsp because im that impressed with it

 

ok let me know if you sell your dsp

 

What made you deside to switch from the DSP to the SC? Just curious bc I just did the same switch but in the opposite direction.

 

So something with less options and no ability for custom tunes is better? The canned tunes themselves have to be comparable gains wise...there's only so much you can do on a near stock gaser. That's where the custom tune and user adjustable options come into play.
