Delete it and make those def problems go away?

Yes it's replaced as asmb

Also make sure the programming recall is done where it puts lower amps to heaters

Prices have come down , I seen a resent post of someone else doing it


But realistically, for a 20 plus , with a ecm , unless you can send yours in , it's around 7 grand for a good install with all the good stuff not just delete

had a 2011 f350 and deleted it. biggest mistake i ever made. had no more power, milage was no better and it stunk like a gross diesel pig when it was idling. i wouldn't park it in the garage because it stunk so bad when i started it. never again!

Depends on who did the delete. Lots of tuners at one point were just deleting the filters and not turning off the post injections or EGR.

My '14 was this way, H&S left half of the post injections on which caused it to stink more in the winter and burn more fuel. Turning the post injections off gained me 15% better mileage even after the delete. It still stinks like a diesel though.

Hp is easy, just add fuel and air. But I've found this powerstroke doesn't "hot rod" like the older Duramax's used to.

Stinks so bad deleted, burn your eyeballs out, leave it alone, get it fixed under warranty, these trucks run great stock.

The fuel mileage increase is very minimal, take you 10 years or more to recoup it.

one piece of good news is when i dropped the truck off at 7am the parts manager told me they have new def tanks stacked up like firewood in the corner. i guess there is a little bit of an issue here lol.
service writer also said they will reprogram also as tex suggested.

My brother's sat at Murray's in the Hat from Feb to June waiting for a tank. It was the height of the "supply chain" issues. He was told GM was looking for a new tank manufacturer. They did give him a loaner though.

He said there was 2 updates. One for the DEF heater amp draw and another for the regen temp. He said don't do the regen temp update. He figures truck lost .7 to .8L/100 and lots of people bitching on the internet about the fuel economy after the update.

just got a call from davis that truck is ready. new tank, tank harness, nox sensor update, voltage update for heater. no regen update.
happy camper!!!

My 2016 was the same Tank heaters Tanks EGT sensors and 9th injector problems Thing ch!t the bed on the way to rocky and that was the end of the emissions for it But it’s a LML so it was about 2500 to delete

my f350 was 2500 to delete. i just hated the stench. growing up around equipment and being in the patch for years i just don't want to smell it. this truck has 7 years warranty on it also so don't want to compromise that either.

Ya I hate the smell as well,, being in a shop with trucks mostly it gives me a bad headache if someone else runs a diesel in . The emissions are a big pain
