Should I delete? Delete comparison

"I would do it if I didn't live in an area with emissions testing'

Is that the kind of country you want to live in, IdaD? If you won't get caught, its OK? So if I won't get caught running red lights in Idaho its OK? Is that how you want me to behave?

So your son decided that he didn't agree with Federal smog control laws and just decided to take matters into his own hands...and violate the law? Pollute the air far more than you...until you decide to "delete?" And since no one will probably catch him, its OK, right? Is that how you raised him?

No, not necessarily. The reason why a diesel "rolls coal" is because it is dumping a lot of fuel with not enough air to burn it. Today's diesels with higher injection pressures, multiple injection events, and quick spooling variable geometry turbos can run deleted without a puff of black smoke. Of course higher horsepower tunes will blow smoke as soon as you get on it. but will clear up as soon as the turbo catches up to the amount of fuel being injected.

You can also purposely tune the truck to blow smoke, the people who do that are just diesel fuel wasting a$$ hats.

WOW! Here is a post that solves all the emission issues with diesel engines! I wonder why the engineers in the industry didn't think of this! I hope the OP patents his findings so he can profit from them. Just as soon as the manufacturers read this post, they will be changing their engines for sure.

I know you are being sarcastic, but why would it solve all the emission issues? My post was referring to "rolling coal" (i.e. black smoke) and how a diesel engine creates it, not emissions like you are stating. Two different things in that context.

Although, the things that I mentioned were added to diesels over the last decade in part to reduce particulate matter/black smoke in order to meet 2004 diesel emissions regulations. So deleting a current model truck with a moderate power level tune is almost like having a 2004-2006 emissions compliant diesel. If someone is complaining about that and drives a vehicle from the 90's(or pre 2004 emissions level) then they are a hypocrite since they are likely emitting more emissions than a close to stock power level deleted modern diesel.

Having said that, I would not buy a new truck and delete the emissions hardware / software either. But I'm not buying one.

1) Doing a delete is illegal. Enforcement may be sparse to non-existent in most of the country, but if you're a business owner, odds of getting reported and fined became much higher.

2) Ford has a "no-touch" policy on trucks that are deleted. Dealers are not so supposed to perform any warranty work on a deleted truck. Furthermore, deleting the truck requires a programming. There's no way to remove the "bread-crumbs" left behind, even if you restore to stock, which Ford can use to deny powertrain warranty claims.

3) The stock 6.7L makes almost double to the HP and torque of a the 7.3L. When you say your son's truck reminds you of the 7.3, are you saying it feels slower? And noisier? Besides purchase repair costs, I see zero advantages of a 7.3L over a 6.7L...

Myself, I see lots of advantages in a 7.3 because I have one. No payment book is the big advantage, better fuel mileage is another. I get 18 empty and 15 pulling. My 7.3 has all the right parts inside like forged connecting rods and head bolts that don't stretch plus you can actually fix it because it's OBS so the motor is exposed instead of tucked under the cowl. The big advantage for me (besides it's been paid for, for 13 years now is, no emissions hardware at all. Nothing, not even crank case blowby into the turbo, it has a road draft tube.

I just had it in to the dealer (where I bought it new) for a recall update and not only did they have no issue working on it, they took pictures of it to hang on the wall. It has no corrosion whatsoever, basically in pristine condition, and will stay that way. It's stone reliable and it smokes when I press on the fuel pedal plus it has that sweet (to me) diesel clatter and with a straight exhaust, the turbo whistles all the time...Music to my ears.

The motor is all stock except for a Banks Quick Spool turbine housing and turbo back 5" exhaust, K&N free flow tuned intake with Riff-Raff boots.

I expect the truck will outlive me. Great truck and yes, it's a 4x4 crew cab long bed with a real transfer case **** lever on the floor and manual hubs.

Just fine with me. I do use DEF for something however. I spray DEF on my hayfields as liquid fertilizer. Works well for that.

My 2 cents plus some...

Last I checked the delete and tune cost around $1200 as a DIY install. 6-8 hours of labor if you pay someone else to do it. Even at $1200 I would need 100 fill ups to break even, assuming if I got the 2 mpg improvement most web sites state is the MAX you may get. I admit that 2 mpg if it is towing is a good deal but my mechanic said most people do not get any improved mileage towing. They get little if any driving around town and the majority of the improvement is on the highway without a load.

However, it is suppose to help keep your engine healthy longer also and that may be a good enough reason.

Yes, no emission testing here, never will be.
Everything can be returned to stock in a day.

Lots of positives, no Def, better breathing motor, better mpg

As far as emissions, how much more when you compare 5 more mpg,
No more very RICH DPF operations.
Warranty not a concern.

But still I am a stock truck guy so very big leap for me

Why do you say "warranty not a concern" ???

Machzer, you may want to quantify the advantages first.
Yes it's healthier for the engine if you go full on delete egr and everything.
Deleting does not make it faster. Tuning makes more power. Can do it with or without emissions. Without is easier to make more though.
5mpg claim is likely false. Pre Def/scr trucks that was a reality. Now much more modest gains in mpg if much at all.

IF I had a new rig personal opinion I'd run it emissions in tact (daily driver not a hot rod or toy) unless issues arrived that were more cumbersome than deleting.
After warranty was up, same thing.

He's right.
Might want to be a little more well read about diesel emissions before asserting that.
Shiner never said it didn't caus anymore emissions to be emitted. There's more to emissions than the black smoke.

Yup. Blacked out an intersection in Ephrata just yesterday! Lol
Not really.....but I could have.....
Op didn't mask about the moral implications.
