Hey guys! I am the proud owner of a 2005 ram 1500 4x4 quad cab with the 4.7L V8. I am a part of an all Chevy family, but I must say that I absolutly love my Ram and wouldn't trade it for anything esle except for maybe a hemi. but i think that the 4.7 still has a lot of power and probably gets a little better mileage. I am right now getting about 12MPG in a mixed driving favoring more towards the city side. I am driving it pretty softly too. I am running stock everything exect for my tires. It came with 285x70x17 (basically a 33X11.5) Khumo A/T's which ride amazingly quit and smooth. Anyways I was wondering what I could do to improve my gas mileage and add a little power. In a week I am going to add dual out the rear flowmaster's (2.5in pipe/3in outlets) coming out of a 40 series muffler. In another month or so I am also going to put a K&N 77 series cold air intake in along with new spark plugs. Any other suggestions? Thanks

 

a very long read
with dozens of mods that work:

https://dodgeforum.com/m_447500/tm.htm

in a nutshell
learn to drive like a 'Hypermiler'
consider an electric block heater if you do short trips
when tire buying is near...pay attention to rolling resistance
consider some easy aero mods to make your truck slip through the wind using less hp

 

Do a search on this, there is a ton of stuff.

 

CAI, cat-back exhaust and a tuner are usually the first three mods people go for. Solid gains in both the HP & MPG departments, they work with each other in concert for better gains than each would net individually, costs on each are relatively low & installation is simple. A lot of guys do these three and stop right there...
