| Can’t get mpg up Hey everyone. So o have a 2009 t660 cm871 roughly 800k I started driving by the boost guage 58mph. Somedays I get 7.5-8 mpg and some days 5.5. Mpg. What am I doing wrong. I did egr tune. Replaced all sensors with Cummins oem. I keep boost close to zero while driving and never go over 20 psi while climbing. Any help would be greatly appreciated. | |||
