Where did u get delete kit?it didn't take much convincing for me. I was pulling my 5th wheel with the jeep behind it from Texas to North Dakota and used 22.5 gallons of def. My exhaust was so hot it melted the paint off my exhaust tip. I could drive for about an hour after a fill up before the truck felt like it was running on 1/2 power. I'd have to shift down to 5th for about 20 minutes then I could grab 6th again and have power back. This was on flat ground. I seriously thought my truck with 9k miles on it was going to leave me stranded. I ordered the delete parts as soon as I got there! I've put about 10k more miles pulling the same load and haven't had another issue. The way I look at it my truck will be in a lot better shape internally by the time my warranty would've ran out vs leaving the stuff on.
