Yes James, I noticed it straight away. Better response from take off and better low down torque.
I haven't experienced the Hot tune but can say that you wouldn't want much more power & torque that the Eco tune provides.

Cheers, Craig

HI james_2k -
the DPF delete is an option that you don't need, so consider this: do as I did. Purchase the Eco tune and the tune loader tool. Then purchase the hot tune as an option. You can have your factory tune, the Eco tune, and the Hot tune all stored in the tool's memory. It takes a few minutes to re-flash between tunes. You can select the right one for the situation! Please remember that if you have a swirl motor failure and you load the factory tune, you will get a CEL. As long as you run a GDE tune (either one) your swirl motor will be defeated and no CEL.

I have tried them both and run the HOT tune.

They both reduce the pedal lag about the same. The hot tune has way better performance, but it will hold the gear longer so you get about 1 mpg less.

Either one makes an incredible difference. worth every penny.

Does anyone have any information about towing with the race tune or Eco tune. I tow my camper that fully loaded ranges from about 5000 to 6000 pounds. I know with other diesels you should not pull with a race tune but does that affect anything with this race tune.
Thanks in advance.

I know that in Australia it does not come with a DPF, as it does in the States. Looks like you guys in Scotland lucked out as well. As others have mentioned, Keith bases his tune off yours (you download it from the ECU, send it to him and he sends you the modified one, which you re-upload to the ECU), so I am sure it will show up on his end you do not have a DPF or need a delete.
I have the ECO and it is a big difference over stock. I do not get the great mileage others get, but still it is vastly improved. It boosts sooner, is smoother and you overall have more throttle response. Can't speak for the HOT, but the ECO makes it a different truck already, so you can't go wrong.

FYI you can order both tunes for some dollars more. The device holds 3 tunes, so keeping your OEM you can have 2 tunes on the device and switch tunes on your jeep.

The race tunes will run the turbo hotter, but I don't have an EGT guage (yet) on the jeep so I don't know how much hotter. I was thinking of putting a dual pod with EGT and trans temp. I know they make a dual pod, not sure if they make a 3 pod for egt/temp/boost ?

I bought an 07 CRD a couple months ago, and assumed it was stock. After driving it for a couple thousand miles and getting 26.5-27.5 mpgs every tank, Ive realized its probably tuned already. Is there any way to determine what tune is done to it? Also, the DPF is still in place and I plan on dropping it to see if the insides are still in it. If they are, is there any way to add a DPF delete to an existing, unknown tune?

you may right about it being tuned already, but in order to do anything more with it you'll need to find out what tune you have. It's a fair bet that it's tuned by GDE - perhaps Keith has a record of it (I think the VIN is one of the values read by his flash tool)?

Im new to this forum but anyways wanted to get some peoples opinions on my GDE Eco Tune I purchased this summer (now returned) I put 10k miles on my jeep switching on and off the eco tune. My 07 CRD had 92,000 miles on it when I bought the GDE tune in hopes to get better MPG's and fix the power loss with the larger tires I had installed a year earlier. Before the tune I would average 22mpg 70% highway 30% city. Instantly after installing the tune my jeep had a much louder idle sound and when I accelerated it would put out a knocking sound kind of like an old cummins or Powerstroke. Keith from GDE said it sounded like bad rockers, but when I uninstalled the tune my CRD would purr at idle and sound normal when accelerating. Anyways I drove 2k with the tune installed and my mpg's decreased from 22 to high 19's. Went back to the stock tune for 2k or so and my mpg's went up to mid 21's. its been 3 months now with no tune and my Jeep is running just like it use to stock and is getting mid 21's. I have not been able to get 22mpg's again since the tune has been uninstalled.

Has anyone had this problem occur to their CRD? Any thoughts of why my CRD acted this way would be awesome. I have been thinking about doing a DPF delete but an not sure if I would consider going back to a GDE tune. is it possible to only do a DPF delete and no tune?

here is a link of what my engine sounded like with the ECO tune installed. http://www.youtube.com/watch?v=gMYxR...ature=youtu.be

There was a fair amount of wind nose in that video, but the engine definitely sounded like it was having a problem under acceleration. I haven't experienced anything like that with mine.
