Re: ATF: Bighorn - Bully Dog or Edge
I noticed my EGT's and overall temps were higher in level 2 (tow tune) on the Edge so the last time I towed with that truck I used #3 tune.
I do agree I liked the Banks system, we had it before the Edge and it completely died out on us on a trip, also for those with with an '11 or newer GMC, Ford or Dodge...Banks doesn't make anything for us yet.
If you are only wanting to keep an eye on temps without programmer. I'd suggest the EDGE Insight CTS.
My buddy also swears by EFI Live on his Duramax since it's easier to get a program for your specific needs rather than something out of the box.
