I would love to delete mine asap. At about 1300 miles, my dpf is already giving me issues. Hard part is finding a company that actually supplies the parts/tuning to do it, especially with how hard the epa is coming down on people now.
Whats your plans?
Trying to find out what everyone is planning to do as far as performance. New diesel owner (happily might I add) midsize truck finally went diesel in the U.S. so school me up! Warranty void in mind what is everyone planning on doing to increase them horses as well as fuel economy & longevity?

What are you deleting? The best part about warranties is that you're covered regardless keeping in mind the issues that arise are brought to their attention prior to its termination. Keep a good log and you should be fineI would love to delete mine asap. At about 1300 miles, my dpf is already giving me issues.

I am wanting to delete the def/dpf by basically having a full exhaust kit on it and then tuning it. I have talked to a couple of guys at my dealership about my issue and just got blown off as my driving habits. But recently I have talked to someone and he just told me to take pics of it happening so I can have evidence; which I did I drive the same 30 miles one day every day and it seems like every other day my trip average changes from 33mpg to 21 mpg which is killing my overall average. I am stuck at 22mpg for tanks average. So I gave him the pics and sent it on to his manager who is supposed to take it up with GMC so hopefully find a fix. If they can find a fix that doesn't void my warranty plus extra $, yea I will take it and just delete it later, but if they don't or I continue to have this issue, I will delete since the mpgs was a big reason why I chose this truck in the first place.What are you deleting?

I know a few buddies who've bypassed their dpf/def through all sorts of ways and increased MPG on their duallies but they're models were older, sorry to hear you're having issues have you tried a consistent startup/warmup procedure or do you just hop in and go every time? Cruise control is also a huge variable and most of my experience and research has taught me to avoid cruise control at all costs (hills, other cars putting that huge effect) just some food for thoughtI am wanting to delete the def/dpf by basically having a full exhaust kit on it and then tuning it.

I keep the truck in the garage, right now it has been 70-90 day and night, my drive is pretty flat with my cruise set on 70 everytime. About 25miles out of the 30 miles is all highway and my mpg figures are from where I reset the average as soon as I set my cruise on the highway and check it as I am getting off my exit. When I got the 33 and 21 was both the same way, so its not like downhill then uphill back. One was on a Monday then a Tuesday. So I have eliminated all other variables and I shouldn't be seeing that kind of difference in mpg like that. I have talked to a few trusted diesel mechanics and they all came up with is that the truck is trying to go into a regen cycle. I was planning on getting like a 12 or 14ft trailer, since my little 5ft bed isn't going to get much work done, but if I can take that $1500 I was going to spend on a trailer for deletes/tuning so I can get better, consistent mileage, it would be worth it to me, plus never have to deal with filling up the def tank.I know a few buddies who've bypassed their dpf/def through all sorts of ways and increased MPG on their duallies but they're models were older, sorry to hear you're having issues have you tried a consistent startup/warmup procedure or do you just hop in and go every time?

Every diesel truck owner i know run their trucks hard once a week. How they translated that to me was they opened it up on the road. This according to my friends cleans out sump tanks, and another collection point. I haven't done this on my diesel but for sure have done it on my gasoline engines. Im sure ill stick to the same routine but as for your variation of MPG I would put a code reader in it to start with, and maybe consider an oil change to dump out those shavings from your breakin. I am also working on upgrading my exhaust soon so if you decide to go that route let me know how it works out bud, sorry for the frustrations.I keep the truck in the garage, right now it has been 70-90 day and night, my drive is pretty flat with my cruise set on 70 everytime.

I have been basically giving it 100% throttle every chance I get and it is no change, still varying mileage, every other day. I am going to take it on a 800 mile round trip this weekend and see if that helps finish out that regen cycle that I think it is trying to do(even though I was told a prompt on the dic should pop up when that is happening.) But if not I will just hound my dealer some more until they do something. I have seen some nice partial aFe exhaust kits off amazon for pretty decent price to at least get rid of the muffler.Every diesel truck owner i know run their trucks hard once a week.

My first mod I'm going to do is a diy spray in Bedliner, my husband did my other two trucks and they both came out great. I don't like not having a Bedliner, after that I don't know what else I'll do to it yet.
I am going to drop a Winch inside the useful parts of that front end. Hopefully have enough room for a led light bar as well as the immediate removal of that pesky front skirt. I was off road a bit today and WOW it is very annoying having 8" of ground clearance in the front. Otherwise the truck held it like a monster. I am excited to see how everyone deals with this front end who plan on having the capability of driving in areas cars cannot access. So far the truck has performed like a champion just a couple of touches will make this the truck for me.

Have you, or anyone looked into an aftermarket replacement for the nose dam? I am not a fan of it, but I don't like exposing my hangy down parts. (both truck and personal). Either a skid plate or some other method of hiding/protecting the nuts and other hardware down below (I'm still talking about the truck)...I am going to drop a Winch inside the useful parts of that front end.

Zone leveling kit (need to install)
Intake (aFe stage 2 lists 21ft lbs)
LED in front bumper
Exhaust - waiting to see who comes out with what
Tuner (open to suggestions - maybe spade or the future one aFe will likely produce)
Winch (prefer inside bumper mount)
Likely in that order too ;-)

These guys have a killer front and rear bumper for the colorado with the winch setup as far as a lift goes I am waiting for BDS to offer their setup.
