We deleted my dad's '07.5 6.7

He is running the Smarty Jr ME.

In his case it was the only way to keep that POS out of the dealers service dept.

^^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.
