Hey there just wondering whats the ultimate programmer or chip for fuel milage for 06 CTD. Thanks

 

I picked up about 3mpg max with the Quad X2.

 

If looking for just a mild upgrade and good mialage a Smarty Jr, or just the regular Smarty seem to turn decent results with proper driving habbits.

Same here with the X2, running the max mileage tune on setting #1.

 

My wife's 2wd Mega Cab picked up 4mpg with a Superchip's programmer & a solid 5 - 7 mpg with a Dr. Performance Predator module, 110hp - 220tq). She's been running it for 25,000 + miles with zero complaints.

 

at last check with pen and paper, I am geeting 22.8mpg with the bully dog and the crazy larry tune. Now thats flat land driving 75mph and under on the hiway, stop sign to stop sign in town, and a short 10 mile trip with the horse taxi on the tank I checked.
