I have a ram 1500 quad cab 5.7L. everything is stock besides K&N air filter and I put 35s on with 17in wheels. My system says i was 10-12mpg before now i get around 13. I am still looking to improve the millage with a cold air intake and exhaust, any ideas or help on what has worked?

 

Welcome aboard. Sorry to burst your bubble, but a CAI and exhaust will do nothing for your mileage. If you're relying on the "system" for accurate mileage numbers, you're being mislead.

 

Aside from getting a small car, not much is going help in the way of fuel economy. I have a CAI and exhaust and a tuner and it worse cause I can't keep my foot out of the pedal.

 

thank you for the info. any other ways to improve the gas millage? besides go easy on the peddle

 

This thread comes up DAILY, so you might want to do a search or just start looking at titles on the first few pages of threads.

But the big things are the simplest. Tune Up, switch to synthetic fluids, proper tire inflation, clean throttle body and EGR/PCV valves...

 

What year is the truck? With 35's, you can actually gain some mpg by going to 4.56 gears. It will be costly and take forever to gain back your money in gas savings.
A programmer such as Diablosport or Superchips. Diablo now has a MPG tune that seems to have helped mine. I was up to 19mpg in mixed driving, but I am now taking a hit due to winter blend gas and colder temps causing a little richer mixture.

 

Tuners are the only thing that I've witnessed actually help gas mileage, oh and turboes, lol

 

Start drafting tractor trailers....haha

I have a Superchips tuner with improved transmission shifts that I created. I have an '08 with mds disabled, stock tire size, and I get 14mpg mixed. Generally 11-12city when I'm rough or towing/15-16highway
I have a commuter car I use to save on gas. Even with the cost of insurance and the car itself, I still save money for the gas I would have spent on the truck. That means the car has paid for itself, so in reality...I have a free car just because I drove it for a year.

Buying a tuner for sole purpose of saving mpg's is not what I would reccomend. The added performance benfits along with some mpg's is what makes it worth it. Without the trans tuning, I actually lost mpg's going to a tuner. Raising the shift points brought me back up to stock mpg's AND gave me added performance and ****ing improvements.

 

It's kinda funny that guys around here are commenting about bad mileage. I didn't buy my truck for the mpg's and don't think most people do. Bought it for the looks, power, capability, the mileage was the last thing on my mind. I don't mind getting only 12 mpg. If I wanted a car that gets good mileage, woulda bought a butt ugly prius. Just my 2 cents.
