Do you have a GDE tune on your CRD?


My 05 is tuned, with more torque and better economy. The best I saw before doing mods was in the mid to lower 30's. I really have not checked it a very long time. I have felt no loss of power with a lift and bigger tires. Most likely that is because of the Eco-tune. Mileage is back down to the mid and higher 20's range as a best guess.

When we went from the stock tire to BFG All terrains, our CRD lost 3mpg. We are not running a lift, but others with a 2-2.5 inch lift lost on average another 1-2mpg. There is a penalty off road capability, but it is worth it if ever needed.

Hope it works out

Regear if going to a lift and larger tires, just like a gasser CRDs can also benefit from swapping gears. Lots of folks have done it with great results, but some think the CRD has enough power that it doesn't make any difference.

I haven't talked to you all in quite awhile. I very much did appreciate you guys tracking me down for the parking lot meet n greet and the tune.

You were definitely a 'first adopter' of the GDE tune. Good to hear your CRD is still running well. The earlier a tune is applied on that vehicle, the fewer problems down the road. We have a building now and no longer do the roadside tunes.

WHAT ! No more roadside tunes? Ha ha - oh well.

I think I was like number 2 or 3 for that early tune, it only had like 17K for miles - still love the changes it made to that little tractor. Was like night and day. And no EGR worries!

Congrats on the building and all the work that went into development.
