Ok so lets hear some honest answers from the guys who have done deletes on their trucks. I have a 2009 Dodge Ram 2500 6.7L engine with 3.73 rear end.
I am looking to see what is the best DPF delete kit out there, the cost etc.
I would also like to know how the mileage was affected before and after the delete was installed and same for performance. And exactly what performance gains you got.
I am seriously considering a DPF delete kit, but I am unsure which one to get and what problems if any I will have once I install it. Knock on wood, over 20,000 miles on my truck now and no problems thus far.
Also, is it better to go with stacks or a cat back exhaust ? I would like to see if there would actually be a difference.
I have 2008 6.7 w/3.73 rear. Did deletes get 18 mpg. No problems. Did have problems before deletes around 30K, the dpf clogged up w/soot, and O2 sensor. Truck runs 100% better w/deletes. I used HS performance XRT.
All of the numbers are hand calculated. Just did the deletes, i pieced together my deletes, bought a used smarty and delete pipe. I used a $2 freeze plug to block off my egr. I was getting 18 mpg going up into the rockies and back, now im getting 21.1 and 21.2 on two tanks. On the 21.2 tank i did about an hour of 5-10 miles per hour. It was snowing so i went slow up the mountain which saved some fuel.
Generally on the highway i was getting 21 mpg on a tank of 100% freeway (i drive 65). The highest i ever got stock was 23.1 driving across nevada with no wind and cruising at 60 mph. Havent had a chance to get a full tank off highway in yet but im expecting something like 23 or so.
edit: you really dont need a kit, its much cheaper to find some used parts. There is no difference between a new programmer and used one, except the price!
I agree. Get a delete pipe and a used Smarty. I would suggest a 5" turbo back with muffler.
I'm getting 18 mpg hand calculated. My truck will smoke the rear tires if I want it to and im on "economy" mode. Runs much better than ever.
Truck per sig. Bought it used with 23K miles, did deletes almost immediate after purchase. Overhead was saying 14.5 mpg on winter fuel before deletes. Now with all highway I get over 19 mpg, usually about 16 mpg with daily driving which is mixed city/hwy. I do notice LOTS more power after deletes and mods. Also I know the engine will last much longer without all that soot going thru the intake.

I did the Deletes and use an XRT didn't delete the ERG just turned it off and unhooked it.
I get 19-21 around the city and 23-24 on the highway. i normally run 70-77 on the highway.
truck has been deleted for about 6 months
2007.5 Ram 2500 QCSB, 4x4, G56 6spd, lvling kit, AFE stage2 intake, Amsol dual remote bypass filter, XRT, Valair DD clutch, and other things fell off
I bought my truck brand new and right at 10,000 miles the truck went into limp mode. Drove it to the dealer and they had it for three weeks, cleaned out egr, and turbo. Made it another 15,000 miles and did the same thing. Before deletes the truck got 21 mpg cruising 60 mph. I did a 8 inch lift and 37s the mpg droped to 16.5 cruising 60. I put a hypertech on stage 3 and mpg went up to about 19-20. I did a 11 inch lift and 40s and it droped to about 15-16 mpg. Then i did a egr delete and a 5in turbo back straight exhaust, with the xrt on the 175 tune with mild fuel and extreme turbo. My mpg went to about 19 highway and 15-16 town, not bad for 40 inch tires and stock gears. Now im going to about 10inches of lift with 38 inch tires, ill let you know what the milage goes too. The only reason why i did the deletes was because my truck was spending more time at the dealer and i still had a 720 dollar a month payment for a truck i was not able to drive. Not one problem after all deletes, runs perfect.

this may be a dumb question but doing these deletes voids dodges 100k mile warranty right? i have 60k on my 6.7 no problems but i am seeking more fuel mileage and more longevity with a side of power of course...it will be a long time before i reach 100k miles and ive been through a couple turbos already that the dealer paid for because of the warranty, and i doubt i could afford to void that warranty..
