I've got the 3.9L 2006 GTP
what can i do to improve it's fuel mileage? I get 17 avg. (these are my calculations based on the gas and miles, not the computers) around 21ish highway and 15 city.
I don't have a cold air intake or aftermarket exhaust, but what are some things that would be recommended to increase the mpg?
thanks!
