Hypothetical Cummins EGR delete questions

According to @Loganwayne and his "friend" from the infamous Harlan wedding crash and the bylaws of what constitutes homo/no homo relations: it's only homo if BOTH Crocs want to touch. If only one does, it's no homo.

Are those hand calculated or from the dash. No one on any of the forums I follow had ever shown hand calculated numbers with that much improvement on a 2012 or newer cummins. The tires and gears also makes me think it is not real. 5in exhaust is a waste on this motor as well. If you see any MpG improvement real world. Just added stress on the Trans and if you have the Aisin there are no tunes for it at all. Unless you are out of warranty and having emission equipment issues there is no good reason to delete a 6.7.

With those gains I’d say it’s well worth deleting one. Being as I know Jody’s friend as well, I believe those numbers. I have no doubt believing it because I’ve also experienced it first hand with @edward truck. 14mpg towing a heavy trailer shaped like a billboard, and regular 22mpg empty using cruise and a light foot, all deletes on a 40HP tow tune. All hand calculated.

However I will say, it worked well for a while but eventually the clutch started to slip with regular driving. He went with a Southbend and upgraded the master/slave while at it. Never looked back.

It is just the unicorn then. Very few people ever get any return on a delete and with a G56 he will be replacing a clutch soon. To me unless it is out of warranty and having issues with the emission system it is just not worth it.
 
Yeah extra fuel mileage and power is dumb. He should have never upgraded it.

Jody tell your friend to return the truck to stock cause this wasn’t worth doing.

While your at it, might as well take the Chromo shafts out of your Ranger. I know they help the truck handle the extra power and give you peace of mind, but you shouldn’t upgrade till you’re having problems, there’s absolutely no reason to prevent a problem before it becomes a problem.
 
I wouldn't trust that Jody guy. He'll take a photo of you killing a climb, and photchop his rig into the frame to take the credit

I appreciate the dialogue. Seriously.
After the turbo was replaced just under warranty (by time) due to sticking caused by soot build up (would have been a $2k repair out of pocket) it was time preventatively do some upgrades as this truck is to last the owner a long, long time.
We all know the issues a failed/failing EGR system can cause on a diesel. Incidentally, the owner was a diesel tech at the local Dodge dealer for quite a while. His thoughts are by removing the potentially damaging items and doing an extremely mild tune (OEM clutch safe) he will see even longer life out of the truck.
He's beyond any bro dozing years and is still yet to see and sooting on his bumper post-tune.

You don't think "I" would do anything like THAT, do you?

Not sure it's a matter of worth it or not. But if you want your truck to look like this then by all means keep your junk stock.

all three of my 6.7’s have been like that when I opened them up to do the delete. Opened my 2010 back up when I put a new airhorn on after about 100k and it was as clean as when I cleaned it out during the delete; maybe cleaner.

Just my thoughts. People can do what they want. But there are a bunch of trucks on other forums with 400k plus miles and bone stock with no issues. If you work it hard it will live a long time bone stock. If you daily drive it and never put a load on it you are not doing the motor justice.

Most of the issues I see on the various Cummins forums are on tuned trucks.

I feel like this picture, and this personal experience from @skyhighZJ, overrides something just read on the inter webs. Not every truck is being driven super hard and/or towing heavy to keep it cleaned out. In that case, seems perfectly justifiable to delete it and put a SAFE tune on it. Emphasis on safe. If he has to put a clutch in it, so be it. That’s $1500ish for even MORE peace of mind and reliability.

Not everyone is driving these trucks on a hot tune like a pissed off teenager on a drag strip abusing them.

Plus it's not like a clutch isn't a serviceable item, and the stocker isn't know for it's awesomeness anyway so that point is null.

Agreed. As far as I recall that is the only drawback of that transmission. My understanding is it’s a very good and sought after transmission. Conver is the first I’ve seen to be a nay sayer.
It’s also very common to need to upgrade the clutch on any vehicle you add power and torque too.

I feel like it’s the same as saying “you shouldn’t turbo your LS motor because the transmission won’t take the extra power, and the motor is plenty strong stock”. That’s pretty lame.

Time well tell, as I bet Jody’s friend won’t sell the truck anytime in the near future and will report back after many miles.
 
So if for nothing else I deleted mine cause, well, I don’t have the money to be replacing DPF components or egr components or any other number of parts when the egr cooler cracks and dumps coolant into the exhaust manifold or XYZ... the only thing my timer does is make the motor run and I have bumped it up 1 time to see what happened and put it back on the 30hp “stock” tune.
 
I am not anti delete. Once my warranty expires which is a long way off I might delete and if something fails I will definitely delete.

EPA is cracking down though so it will get tougher and tougher to do.

I just don't need more power and I cannot afford to toss out a warranty at this point on a 2018 truck.

Tuning has come a long way. You can now leave EGR installed. Simply bolt in a DPF replacement pipe with muffler and go on your way. If you ever have to go in for warranty (assuming you didnt do any "bruh" raceme crap), you can simply plug back in your egr and bolt back in your DPF, spend a couple more minutes changing the tune back to stock and drive on to the dealership.

There is a smart way to tune/delete, and not-so-smart way. Like with all things! haha
