This is my hope as well to be able to do this all in one step and then swap them all over at the same time. I'd like to hit high 20's mpg on the highway just cruising at 60-65mph. I'd also add in the K&N filter and likely do the turbo resonator pipe as well to free up intake and exhaust air going in.

On a side note: We are almost finshed validating a DPF delete tune. Early data is showing a decent increase in fuel economy around 2 mpg. There is virtually no smoke exiting the tailpipe even without a DPF installed. The Merc engine is very clean. Coupled with the ECO tune the fuel economy gain can be up to 3-6 mpg.

The DPF itself was just gutted, then refit in place and all sensors remain in factory configuration. The face of the DPF was 60-80% clogged from ash. PO did not use the "low ash" oil apparently. Based on feedback, the exhaust tone is not noticeabley different w/o DPF brick.
What would be the difference between your tune and customspooling tune ?
Is the concept the same ? One power tune and one eco tune both having egr and dpf delete ?

For North America we currently have our WK ECO tune and within a couple weeks we will add the DPF delete option for this tune. The option will add $100 to the tune package.

We will investigate building a delete pipe for the DPF, but this may take a little more time to have available. Not sure on pricing for the pipe as we have not looked into a quote yet. Being stainless steel with flanges, I would expect it to be under $200 hopefully.

I have no idea how the custom spooling tune compares to the GDE tune. Does anyone know how much their tune costs w/ a flash programmer tool included?

Since the ECO tune with DPF delete currently makes no smoke, we can surely create a HOT tune option in the coming months to amp up the performance more. I guess this would be for those that just can't have too much power underneath their right foot!

So current customers will have to pay $100 for the DPF delete?

When i cruise at 85 mph I get 20.1 mpg ... my engine OEM no mods.

Deleting the DPF has to do with dealing with a a major plug. If it is not removed you really can't get any performance air-fuel mod's.
Personally i think if you want a build an offroad only race truck, if do not remove the DPF then you will get no gain on engine mods. it's a no-brainer old school. more Air & fuel .. without an exit will get you not much gain.

... And please without damageing the engine or side effects. When Dpf deleting does that mean the regen cycles (750 miles ish) will be completly turned off ?

The current price of our DPF Delete Tune (Economy and Performance) is $1125 including the flash tool and both tunes. This includes minimizing or disabling EGR.

[QUOTE=jediknight;14006596]... And please without damageing the engine or side effects. QUOTE]

Exactly.
One thing to keep in mind is that the fuel system and air system including the turbo all are designed to have optimal performance within certain limits. I'm sure GDE is within these limits - but it doesn't take alot variation in pressure and flow to severly shorten the life of the fuel system.

On the turbo side, you need to maintain a certain amount of backpressure in the exhaust system or you may risk a turbo overspeed.

I am also interested in the GDE tune - although I would like to be reassured that they have taken the component limitations into account - as we all know how expensive they are to replace...

We used turbo speed sensors, thermocouples and in-cylinder pressure transducers during development of the tunes. Our tune is designed to remain within the factory limits, so as not to shorten the lifespan of the engine. Most customers see a drop in exhaust temps when running our tunes. Thanks, GDE

Couple of quick observations:

1. Fuel mileage (two tanks) is up about 2 mpg over the InmotionUSA tune I had prior to the GDE tune. Awesome!
2. Coolant temps are one mark cooler than when OEM (two marks below 12 o’clock vs. one mark below 12 o’clock)
3. Power delivery and overall drivability is much better than OEM with off-idle lag being better than the Inmotion tune. I never dyno’d the jeep with the InMotion tune, but power feels about the same.
4. Off-idle acceleration is significantly more ‘diesel like’ than OEM and the Inmotion tune. It appears to lessen once the motor warms. Basically sounds like a 7.3 PowerStroke when you accelerate from a stop when cold.

I like the tune and will report back after towing to Pueblo and Hastings over the next month.

thanks, I'd also like to hear your towing experience with the tune.

I will be at Hastings Sept 1/2 with NASA Central region racing Spec Miata. Wonder if that is the event you are going to.

I'm waiting for the DPF delete and replacement pipe before going with the GDE tune (just buy it in one fell swoop - do the intake filter and exhaust as well).

Nope. I'll be there Sept 20-23 with the Mustang Roundup. Was planning on going to the NASA event... but two 8 hour tows back-to-back gets old.

Been there, done that. We (NASA Central Region) are planning on running High Plains sometime next year with NASA RMR (tentative in our schedule).
