DPF del, tune & warranty?

[Caper11]

I had a 08 f350 6.4 running a sct livewire programmers with dpf delete and cold air intake and never had a problem with warranty. Blew my torque converter while traveling through the mountains and had it covered under warranty and have also had a few small issues around town and have never had a problem. Also had a 07.5 dodge 3500 with the 6.7 with a programmer and dpf delete and even the lame dodge dealers in town here covered everything under warranty. Just bought a 2011 dodge 3500 and plan on chipping it and doing all the deletes as soon as I get a few more km on it. Caper11 I don't know how your truck gets 15mpg pulling a travel trailer with no deletes. I was only getting 15 - 16 with mine just pulling a 16' flat deck with a sxs on it. If that is the mileage your getting with out any deletes you are doing good

Not sure how your are calculating your MPG I'm not using the overhead (US) I use canadian numbers with a calculator. I use howes meaner power cleaner every now and than and running empty Ive seen as high as 22MPG hand calculated.
I run stock tires and have a 3.73 gear set and avoid spooling the turbo high, fuel is too expensive these days and I try to drive as efficient as possible.

Canadian (Imperial) gallon = 4.54 liters
US gallon = 3.78 liters

Gives you numbers that are 20% higher if you go by Imp gallons. Makes the wife feel better.

dad has the same truck running a afe cold air intake, dpf delete and edge cs programmer. Dealer in town has no problem with the mods. Would get a check engine light every once and a while without the dpf delete. Once we did it we turned the programmer to the dpf removed mode and are running it on level 1 right now. check engine light is no longer on. gets 14-15l/100km without a trailer. gets 17-18l/100km with a 26' enclosed trailer.
