I am getting around 17-18 with my 08' LMM. Have you had the ECM reflashed lately?

Clean filters, higher tire psi, and up to date ecm flash. Easier on the go peddle.

WHO REFLASHES THE ECM ?

The dealer will be able to tell you if you have the current Rev. level or not. My mileage is 60% highway and 40% city. When people give you their mileage #'s you sould ask what their # consists of. I had a guy tell me 20-21mpg, I said no way. He then told me it was 95% highway driving.

cruise control works for me

My 03 4x4 dually,has exhaust,filter kit,and Edge set to gas milage,it gets around 15-16. Towing boat 10-12,car trailer 9-10

I put the exhaust and air filter kit first and could tell a diff

mike if you use the edge or any other programmer just be careful about your warranty. If they can prove you have one on the truck they will not warranty the motor.

Ask Speedpro!






















sorry.........couldn't help it. :D

DPF and regen is what is killing the new trucks mileage.
