truck is all stock now, egr blocker plate install little later, read many threads on tuners, looking at edge cs and edge cts, whats the difference between the two, wanting something that i can understand pretty easy, main thing is to be used while towing 12k 5er, and little better mileage,so if anyone has one of the two and uses it for towing i would like to hear what you think of yours. thanks

best source of info....www.edgeproducts.com

I think the only real difference is the screen
cs- color screen
cts- color touch screen

Should be ok to tow on a low tune like maybe 1-3 with a stock tranny but don't just hold it to the floor everywhere you tow or you may have problems
