got it done !
ok, I did the delete with the dpf and the h and s tuner, I also did the egr delete kit also, I have to say, you really need some time set aside for that one, I took my time so that I didn't break any bolts off, I will tell you some pointers that really helped me. I removed my front tire and wheel well cover (some one gave me the idea on here) and it made getting to the rear bolts on the cooler and the 10mm nut on the rear a lot easier (if easy is what you want to call it ), I removed the wiring harness from the from underneath the truck with a long screw driver. The bolts on the tube going down onto the intake was about the only thing that was a booger, I kept on spraying them with creep , and I took a long punch and hit the bolt head the next day, still couldn't get them broke loose, then I took my dewalt cordless impact driver , put it on tighten for a second, then they came right out like the weren't even tight at all, I really took a lot of time working on these, as I didn't want to snap them off, I also used the original hose from the truck to go from the bottom of the radiator to the top, worked out well and is underneath the air box so there was no need for the hose with the kit, which was to short anyhow, my truck only has 30,000 miles on it (2011) but the exhaust tubes were really full of soot, not enough to block it or anything like that, but couldn't believe how much was on the sides, kind of like in a flu of a wood burner, truck smells more like diesel now, but it sure does run a lot better, as for gas mileage, the truck gadge (both of them) say 15.4 miles to a gallon, now that is going up a steep mountain everyday, haven't had highway miles yet, but I cant seem to get my foot out of the gas either, it sure makes driving it really fun if you like taking off like a race car...lol. I will do a hand calculation when I fill up to see if they match (by the way) I was getting 10 to 11 miles before the delete, I checked my mileage every time , on the highway I was getting 14, I got a lot better fuel mileage before I put on 35 inch tires, but the mileage was getting worse every year, not sure why, got 21 on the highway when I bought it, 14 towing, then 10 towing last year , who knows, sorry for the long post, if I can help anyone out on the egr delete, send me a message and I will tell you what I know
