DPF Delete Question?
I did some search and havent found what im looking for. Does anyone make a DPF Delete kit that is just that? I'm not wanting to put a big chip or programmer on just want rid of the DPF! Looking for some better milage and no regen!

Spartan Diesel Technologies is your answer. I know you're not looking for big power, but you DO need a programmer and Spartan has a DPF delete tune that is "stock no regen". You won't see any real MPG improvements though. You'd have to get their higher HP tunes for that. Check'em out. They have a lot to offer. They ain't the cheapest, but they are the best. Why go cheap after spending all that $$ on the truck?

I find this hard to believe. If you remove the DPF and run the stock "no regen" tune, you WILL see better gas mileage. For one, you won't be entering the regeneration process, thereby saving fuel. ALSO the exhaust will flow *MUCH* better resulting in better MPG for the entire tank of fuel. I bet you see an easy 2-3 MPG.
I have not seen anyone reporting 2-3 MPG better with straight DPF delete. The only people that are getting that much better MPG are those that are going the DPF & DOC delete with a high HP Spartan tune.
The high HP Spartan tune removes the enviromental lag at take off, re-tunes the injector timing, disables the EGR etc etc
A straight DPF delete tune would leave the environmental lag at take off and the injector timing would still be retarded (for emissions). I can't believe you could get 2-3 MPG increase out of this.

astamp78, you are correct. He won't see 2-3 MPG improvement. That's what I said and it's not any "belief" or "assumption". I run the higher HP tunes and I have run the lower HP tunes. It's the tuning that gives us the MPG's, not the free flowing exhaust. The exhaust is only a part of the equation.

Spartan seems to be the best way to go for a DPF delete to get the best MPG gains. If you want a little better MPG, more power but leave the emissions intact, then I would suggest the Banks tuner.

Spoken like someone with NO actual experience. It's been discussed on here many times and lots of guys will show evidence that simply deleting the DPF doesn't amount to any substantial gain. Maybe 1 MPG better if you drive it easy and tilt your head at the right angle when doing the math. Listen to what the other EXPERIENCED guys said and do the tuning if you do the DPF delete. There are lots of guys jumping on the tuning band wagon now so do some research and find one that's in your budget (if you don't want to shell out for Spartan) but keep in mind that you are saving pennies on something that could cost big $$ down the road.

How high a Spartan tune does a person need to realize an improved MPG?

The 275HP tune seems to yield the best MPG's, but they all improve MPG's incrementally. The problem is, having all that extra power makes it hard to resist putting your foot in it now and then, and playing a little!

Um sorry man but you have absolutely no clue what you are talking about. I drove 30,000 miles in or year. And I know for a fact I average 4mpg better than stock running my Spartan tune. So you can do the math... Based on that I paid for the tuner, dpf delete, and the dashdaq in one year. In 38 years I will have saved roughly $76,000 how bout dem apples

I'm just trying to sort out if it is worth it or not as there seems to be a 50/50 split on its actual value.

I can't justify it's value for what I need. I figured out back when fuel was $4.50 gal. it would take 3 years or so to break even. Then loosing the warranty also taking it down then back for the inspections adds to the burden.
Now some are saying it's better for the engine in the long run so it's not dumping fuel into the crankcase but running more hp would do it more harm I would think. Seems either way we loose.
One guy figured between the EGR deletes,tuner,dpf delete,hoc delete it needs to breathe and run right it would run 4K. I find that ridiculous. I'll trade it in before I do that probably.
