^^THIS^^ is why many delete. While the current emissions systems do a great job of cleaning up the exhaust they have turned diesels which were once considered reliable workhorses into temperamental limp mode vehicles. It is a double edged sword as you will loose any remaining powertrain warranty once you tune.

My BIL 09 RAM was always in the shop for CEL/soot clogged emissions. Even the diesel tech was suggesting to perform a delete to get around the problem. He even said they get trucks in with deletes and they would do everything not to void the warranty. Having said that he didn't want to take the risk of warranty denial that couldn't been covered up by the dealer or the dealer change their policy and just decided to get rid of that truck.

I wouldn't even consider deleting a truck under warranty.

When performing the deletes with a 6.7 cummins and you have to install a programmer to handle the changes. Along with this programmer comes some extra power and the 6.7's head gaskets/head bolts don't play well with the extra power. This is a repair you don't want to have to deal with.

Most if not all delete tuners offer "stock" power level options. So just because you tune to delete the emission doesn't mean one has to crank up the power levels.

I can only speak for GM when it comes to warranty and tuners. It is not a dealer call when it comes to major powertrain warranty claims. GM (corporate) will request an ECM snapshot from the dealer for any major powertrain claims and at that point will be able to tell if the truck has been tuned. In many cases it's not a dealer call regardless of how tight someone is with their dealer.

The OP has a 2012 and unless he is over 100K he still has a full drivetrain warranty. If any modifications/tuner is added they will know it and the warranty is done!

Just want people to be informed of what WILL happen if they mess with their trucks under warranty. I personally don't care. I thought I was going to do deletes when I first bought my RAM but after being fully informed I realized it was a bad idea.

The only reason to do something like that is to buy my last o2 sensor related to it. No more power needed and it is plenty fast enough. I too like the clean burning no smoke part so deleting the dpf is not part of the equation. I know the cooler part, but I don't see how pushing hot, oxygen depleted exhaust back into the engine can be a good thing.

It's not a good thing, but it is what it is these days.

Bull dog is making a programmer for the 6.7 so guess more power is needed for some. If more power is needed buy the new f-350 but that wasn't the question.

Dang Larry....but I agree, Hey, mine has enough HP & TQ, I don't need no stinking delete or tune:)

350HP/800TQ not enough?

It's more than people realize.

I run 415/850 to the ground, so about 490/1000 at the crank and it's very very very very rare that I use more than 80% load when towing, and I've never needed it in 5th or lower.

At 20Klbs combined I can pull 4% grades in OD on a 85° day above 6,000 feet and have yet to find a 7-8% grade I cannot pull at 55-65 (speed depends on the road).

That's with a NV5600 and OD ratio isn't nearly as good as 5th, for towing, on the 68RFE.

I bet I could de-tune 75hp and never feel it with a trailer hooked up.

So I agree, is the cost worth the reward? Trust me I have a lot of cost!! The reward is nice, but sometimes you have to wonder...

Thou it's a cheaper hobby than other things :-)

Looks right inline to me.

There isn't much, if any, reason to delete the EGR and keep the rest of the truck stock. The EGR isn't what is was in 2007.5, even on a 2007.5.

"Not sure why you would want to do that???? For one you will be your own warranty station! You can not clear the codes on these newer trucks. They will know what you have done if you go in for warranty work. For the money spent you most likely won't make up for it in fuel savings. 350HP/800TQ not enough?"

"So someone breaking the EPA laws is going to post here that they do it and don't mind telling everyone in the world about it!"

Not sure what this has to do with the OP's question .....
