Agree with Morty and EV2Demons's mileage numbers. My '01 Cummins w/ 3.54's barely did 18.

Yes Rhino, the MDS does make a difference. Amazingly, guys on the Dodge Truck Forums will go to the ends of the Earth to shut MDS off. shruggy

6.4 is a Winner, but I still think Dodge or Ford need to do a turbocharged gas in a 2500 and up truck. Just 550 torque; that's all it would need to compete with a diesel.

Thanks for the review, Wally. up Keep an eye on those firestones. twocents
