If you don't want to deal with it then I suggest like others to leave it stock on the intake/exhaust then and work it hard. And then hope you don't have to deal with the results of running the emmisions. Doing the deletes is easy and can be done in a couple hours, you don't need a shop to do it that is worrying about a fine. Just keep your deleted equipment for when you "may" need it. That is what I do here in CA, no problem. The deletes are such a better route for long term sustainability, which can easily be put back if/when needed.

Not sure why you'd be willing to bother with the fuel system mods and such but not the simple deletes which is really the single best thing you can do for your truck...

 

This is getting a little off topic but IF the deletes where done on my truck, and I needed dealer service like cleaning of the VGT or something, could they say they are not working on it even tho its out of warrenty? Local diesel shop guy I talked to, said he would not even touch the truck after the deletes unless it was proved to him that it was for offroad use only. So this is what im going by..what the local trusted diesel shop told me...thats what changed my mind for now I guess.

 

If you do the deletes, you won't have to really worry about cleaning the turbo and such. Just make sure your equipment is all good before you delete. You can always put the stuff back if you want or need to take it in for any testing or warantee work... I guess they can refuse to do whatever they want, but I would go somewhere else as that soundd ridiculous to me to not work on a truck you are paying them for that is out of warantee.

There is always some worse case scenario, but I have really yet to know of anyone on this vast forum that has had any real issue after deleting that is related to such.

If you're worried about warantee and or any other federal laws, testing, etc. I would leave it all stock and hope for the best down the road...

 

Gotta be someone out there with 250k on their bone stock 6.7 without any problems.. As most can probably tell this is brand new to me. Its seems that if I dont delete my truck, im going to have extensive repair bills at the dealer, truck is gonna run like crap, etc. This is what I have been led to believe at this point. Case in point, I do respect your guys opinions and what you think would be best for my truck. I appreciate the feedback.

 

Good point. The "passive" regen is going to be a function of the 4th injection event and that controls the temperature of the DPF for cleaning. Any time I was towing in Passive regen, as soon as any load came on, the 4th injection tapered off (read less EGT) until you were back on level ground.

 

Actually thats active regen. Passive regen is anytime the EGT's are hot enough from normal use to burn the DPF off without the 4th or 5th injection event.

 

Ok. I stand corrected.. I don't remember that being in the writeup I got from the TDR.

Either way, I put about 5000 miles on with all stock components and the S-67 software. I never saw a noticeable change in the amounts of ReGens per tank of fuel on the SW3 setting. So for the extra 60hp and loosing the EGR function made the in town mileage better, and the towing mileage wasn't as affected but still improved. Cruising EGT's were the same with or without the S-67.

 

Good info. The EGT's staying the same probably is what helps the regen's from occuring more rapidly.

 

So that I understand this correctly...I could do the EGR delete only, and run a Smarty Jr. to turn off the EGR functions while leaving the DPF system intact. Doing the "Cali" delete to the EGR is all that I'd want to do. I really don't want the hassle of swapping out exhaust system parts when warranty work is required...like if I was 1/2 the country away from home/deleted parts when work is needed.

 

It sounds that its a feasible option, as long as you don't go crazy on the power.

 

Thanks!
I have no desire to bump up the power or make black smoke. I just want a good reliable truck. The heaviest load that I pull is a Work and Play toyhauler that can gross at 11,200. Even with 4 dirt bikes in it/gear/water/etc. it doesn't hit that figure. The truck does a fine job of pulling the trailer as is. I'd just like to eliminate what the EGR pumps back into the oil, and reap the MPG increase that seems to go along with that mod. I have a trip planned to CO in July and I'd hate to be 1,500 miles away from home, needing warranty work and not be able to get it.

 

You do realize that the Smarty isn't untracable on the 6.7 right? Even if you go back to stock the ECM will have traces that you ran a programmer which could effect your warranty.

 

I thought that on the '08's it was untraceable. Is there any programmer that is untraceable?

 

It's only untraceable on the 5.9's.

The only tune for the 6.7 that's untraceable is stock.

 

A Smarty will disable the EGR function and eliminate CEL's that are generated when you disconnect the hardware, correct?
Are you saying that the use of a Smarty to solely do this fuction would still be traceable?
If that's the case, would I be just as far ahead to disable the EGR in such a manner that it could be easily restored to stock? And then just drive with the CEL on... And maybe buy a code reader to periodically check to make sure that there are no codes present other than the EGR related codes?
Or just leave it as is until the extended warranty expires, which is another 50k miles/4 or 5 years? Then it probably won't make sense to mod it.
