questions on superchips

[RI2500]

What are the tunes that you get with it (eco, tow, performance)
does it do anything to the trains or do I need to do that. Should I also do a CAI and cat back exhuast or will a stock truck see gains. I going to be using
the truck mostly for towing around 7k around New england I know the truck can pull stock but I'm looking for upgrades its a 04 2500 with the 5.7.

What tuner are you looking at? The 3865 or cortex does all the good stuff. Shift points, torque management, you can use superchips adjustments or purchase the trans tuning and adjust them yourself

I would say pickup a used SC3865 and add the trans tune option. But when I hear towing I always think gears. CAI and a Cat back are the foundation pieces for the other mods. Good luck..
