My 2006 Ram 3500 4x4 has right at 144,000 miles I on it now, I have kept track of the fuel mileage since new and have seen a steady decrease in it for the last 30,000 miles
I had one injector replaced several years ago and do not know what the normal life span is on them, what is a good number to use to replace them
I've heard that upping the power through the use of a tuner box will help reduce the fuel consumption, true or not
If this is so what is the best box to use?
I drive the truck empty around 99.0 % of the time, I do use it to pull my 24 Ft enclose Pace car trailer with drag race cars in it., the last time I weigh the trailer with my old pump gas Duster in it it weighed right at 8600 Lbs. on the axles. .The new S/P car weighs right at 700 lbs. less
I do have a cab even camper shell on it also, the best mileage I've seen towing the trailer was around 14 MPG.
Empty it use to get a little above 20 MPG, on the last long trip empty I got right at 17.4 MPG
