I have a 2009 Ram XLT, 4x4 Quad, Diablo Predator 91 octane tune, K&N Cold Air Intake, Flowmaster 40 that has dropped 5 mpg in the colder weather.
70 degree day: 14.5 city and 22.1 highway
30 degree day: 10.1 city and 17.1 highway
These are all taking the same exact routes I take each day.
Is this normal for cold weather or should I be looking into this further. Should I rerun the Predator tune and have the ECM relearn for cold weather?
Thanks
