We have a 3500 dual DRW,4 wheel drive,duramax/allison so it is heiver than the 2500hd I get 9-10 towing with the trailer around 14K . I dont think your going to get much more than 10 towing. I get 14 avg combined city /highway driving

Did the full delete and no word of a lie got a hand calculated 24.6MPG highway on a night drive with zero wind with the cruise set at 100km/h so that was a picture perfect "ideal situation" but in a real world day to day i get about 18-20.
Are you worried about the full delete affecting your warranty? I would love to use a programmer but I would hate to do anything to void the 100k power train warranty. Also in AZ we have emissions testing and I wonder if it would have a negative impact on that?
