ive posted here prevoiusly but could not find the thread i started.
i have a 2003 ram 1500 quad cab 5.7l 4x4 and ive done the math on gas mileage and im getting about 9-10 mpg. The truck is mostly stock it has a cold air intake and a flowmaster exhuast stock 20s and all terrain falken tires. The engine in it now is out of a 2004 durango previous engine blew up. I have noticed that the injectors on the 03 ram fit just the 03 hemi and the 04 durango injectors are for 04-09. anybody think this might have something t0 do with it?
