coalsmoke, don't know what else to say. I did the stealth method. Installed the block off plates in the egr valve, took out the flapper in the intake horn, blocked off the egr tube with a 1-1/8" rubber plug, cleaned everything up with carberator cleaner before putting back together. ( you can't imagine how much soot is trapped in these engines). Installed H & S cat, dfp delete kit, and everything took me 1-1/2 hrs. Oh, instead of leaving the plug off to the egr valve, I cut in half way down the wire loom and pluged it back in. If you open the hood you can't tell a thing is different from stock. With the Edge Additude set at clear codes on start-up, the check engine light never comes on. The only code I get if I don't clear it is " egr circut is low"... . daaaaaaaaa wonder why, I cut the wire:-laf:-laf. The truck does not smoke running on stock to level #4. Only when you nail it on level #5 or #6 (hot). I live at 5700' elevation with no issues. I have put over 1500 miles since the delete and have averaged 20. 5 miles per gallon. That's a combination of hard driving, up hills, down hills, flat roads, 75-85 MPH. Before 13-15mph tops. Pulling my 5th wheel 9. 5-10. Haven't pull yet with the new set-up. Egt's 200* less on average, cruise around 725-750*, no re-gen, engine temp 194, trans temp 145, no more turbo timer, cools to 350* instantly. I know I have more power, better spool, no bucking, stalling, coughing, I can't say enough. Oo. It no longer feels it is holding back, ( got rid of that potato in the tail pipe feel). You don't need to worry about the turbo plugging up. The truck is not, I repeat not louder. I have an aftermarket air intake, and can hear a slight turbo whine, not loud, but cool.
All I can say, if you do it you will never go back!!!!! It is night and day comparison, and you will not trade or give up on your truck again. I have own 5 diesels before, 99, 01, 03, 04, & 05 and this is by far is the best running of them all with this simple mod. I can honesly say, I have never had a warranty issue on my other trucks, that I couldn't fix myself. All of my warranty items on the other trucks were not engine or drive train issues.
With only 6700 miles on this truck, I'm not worried about warranty. If the A/C goes out, the door falls off, the rear end bearings goes out, or the trans mission falls out, Dodge will have to warrant it anyway. Fortunally, my other dealer knows what is missing did not cause unrelated items to fail.
