Got a question open to hear any and all comments on. Is bulletproofing the motor a good or bad thing. Has anyone done it to the 6.7 and what did you think. As well as deleting everything and chipping my 15’ super duty I have 90k on it now.

 

There is no talk about the 6.7 needing to be bulletproofed like the 6.0 or 6.4. The only real talk is the HPFP. There are some kits out there that might help prevent disaster but the key is lubricity. Keeping water out of the fuel and adding sose sort of additive to aid in lubricating the fuel system.

 

Cold side intercooler pipe is about it for hard parts.
Like Larry was saying, some measures can be taken in case of poor/contaminated fuel, but if that happens you'll still be seeing your neighborhood tow truck driver.

 

Ok so what about deleting the DEF and other parts

 

It's not necessary and expensive to return to stock.

 

Deleting will make the truck run cooler, give you better fuel mileage, more power, the engine will last longer, and it will be more reliable. The disadvantages are, you won't pass emissions tests if you live in an area where they have them, it voids your warranty, and delete kits and tuning are getting harder to find. You have to decide for yourself if the advantages out weigh the disadvantages. Personally I wouldn't even consider owning a 6.7 or any of the other emissions equipped diesel unless I deleted them.

 

What's an emotions equipped diesel?

While I agree with most of what you wrote, about the advantages, if some guys de yeted for more fuel mileage, most will be disappointed. Many times the mileage isn't better.

There also are many on here who have stock trucks that are very reliable and yes, there are exceptions to every rule. I'm not against de yeted trucks but IMHO, to deyete for the sake of doing it, if your stock truck is running good, I don't agree with. To each his own and not my money. But I will acknowledge the guys who have done it to solve emission problems that either couldn't be fixed or too expensive to. Done...

 

I've noticed this for awhile, and haven't said anything, Overkill. WHY do you not like spelling the word delete? LMAO it's hilarious reading all your de-yete's and de yeted. The boogy man isn't going to come, by you saying/spelling the word DELETE

 

DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE DELETE






HOW'S THIS????

 

Oh no! The EPA just pinged a high alert on your account lol

 

Maybe I just like making up words... To you know, compensate for stuff...

I'm stock so no worries...

Ahh, it's all about the nut behind the wheel, bruh...

 

Great Humor!

Truly, the only reason to delete is if you have issues. To date, with the emissions stuff, I have had zero problems.

A lot depends on your use. That will make a world of difference on the function and health of the systems. Modern emissions on these trucks works best for hwy use and towing.

Having said that, there are plenty we use their trucks daily for in town commuting and such and don't have any issues either.

 

How is it expensive to return to stock? You keep everything you delete. If returning to stock it only costs your time putting parts back on.. of course its not necessary to delete. But if you are having problems with dpf clogging throwing codes etc,thats what gets expensive. Having to replace emissions components out of warranty is expensive.

 

If or most likely when emissions problems start is why I am thinking about deleting ECG and my DEF components. They (all truck manufacturers) restricts the diesel motor so much with all the emissions so much.

 

It all depends on how your driving habits are. If you have some hills to climb while driving, you should be fine. I'll assume by your handle that you do. If you're towing while pulling those inclines, even BETTER. It will keep the EGTs warmer (572 degrees or higher) so the DPF passive regenerates ( where soot burns into ash because temps are high enough to support it so the DPF stays cleaner) so the active regens happen out at 500 miles or more.

As for DEF usage, I have 3.55s and she's a daily driver. I probably get 7k to 8k miles out of a tank of DEF. Some have DEF related codes but I've (knock on wood) never had a problem. I've had my truck for 2 years and 9 months. I'm rapidly approaching 50k miles. I have enough highway mileage with inclines to keep my emissions happy. My regens complete on the same expressway most of the time that climbs in altitude as I head home and South. The regens get up to 1100 to 1200 degrees. Most times at 1100s.

I have a Banks Power iDash 1.8 Data Monster. Senix just acquired the 1.8 Super Gauge. Mine has data logging capacities. Point being is we can monitor our emissions to know when truck is in active regeneration, watch EGTs and see if DPF is passively regenerating. I'm not saying you have to get one but for a guy like myself who likes to know what's going on, who doesn't want to get a "DRIVE TO CLEAN" message which means the DPF is clogged and needs to be cleaned, I like knowing how things are doing. To know when truck is regenning in case I miss the quick "CLEANING EXHAUST FILTER" display on dash and to kind of estimate when truck will BE in regen mode.

As long as your driving is keeping the exhaust hot enough to passive regen and your active regens complete, you probably should have no problems. The EGR is designed with a replaceable core. The DEF components can be bought aftermarket (Dorman) are relatively easy to get to. I was like you. I did some research on DELETING to have some knowledge. Now my quest is to keep her stock and happy.

I have plans for an Airdog to supplement the DFCM (frame filter/pump) to shine the fuel to remove any miniscule air that happens to be in the fuel due to agitation of the tank when truck is moving. I am trying to settle between a Banks or S&B intake to try to attempt to eek out a little more mileage. I get decent mileage now which is usually 15 to 16 mpg. I am looking at Banks Derringer tuner but want to get the Airdog first. I am looking at methanol systems which provides more power, but a cleaner engine and emissions components as well as lower EGTs. But you have to be careful with a stock truck because you don't want to cool it off too much due to regens.

My point is that I want to use the aftermarket to make my engine and emissions last longer and to stay stock. That's my two cents. I'm not against DELETED trucks for the record. YMMV...
