Default ram 1500 4.7 mpg help

seriously gang.... will a cold air intake and a bed cover really help mileage? i put on a flomaster and dual pipes first. that seemed to help. then i put on a cold air intake. while i do feel more umph, my tail pipes have a lot more black soot in them. i wonder if the computer is dumping more gas because of the more air flow? i seemed to have lost 2 mpg on average...... whats the truth about bed covers and programmers really????? do they really help????

thanks gang

The engine may be running a bit rich.

Since you have an exhaust, while it's a good first step, with more capability to move more air out, why not equalize that with more air in? The CAI helps your engine reap the benefit of the CAI.

The programmer will optimize your fuel delivery & timing, making the engine stronger and more efficient. It is the part that brings it all together.

As far as the covers go, I have no idea. I've never tested it. Good luck!

If you are truley getting 4.7MPG, you have problems that throwing all the bolt-on-items you can buy will not fix the problem!

Running a little rich is an under statement.

Start with checking your Ram for factory specs/equipement, get it running right, then start hanging on the mods.

IMHO, a bed cover will never pay for it self, if your talking MPG savings. They are only for security and/or looks.

I believe he means he has a 4.7 engine. At least thats what his profile states.

Im in the same spot with my truck I have the 4.7 with the CAI, flowmaster exhaust and the bed cover I can't seem to get any better the 13.5 if I'm nice to her but on average I get around 12.5 to 13.0 the programer is my next purchase to try and get into the 14's. But it's like I was told about a month ago on this site by someone I didn't buy the truck to get good MPG's...

I'd recommend the DiabloSport Predator programmer. I really like those and how they work, plus I've gotten good results with them. I currently have two Hemi powered vehicles and they both have a Predator on them.

My Ram saw a mileage improvement of 4+ MPG on the highway and 3+ in town after I got the CAI/Exhaust/Programmer on it. I suppose I would get more if I didn't "cruise" on the freeway at 75 vs. 65 and if I could keep my foot outta it around town...but I can't so that's how it is.

The SRT, with a CMR tune put on top of the Predator 91 octane tune, is now a sideways beast...just the way I like it.
Take a look at my Ram Mods link below, go to page 2 and you can see the before and after dyno when the Predator was installed.

Bed covers don't do squat for MPG. As air flows over the cab it creates a vortex in the bed that does the same thing. A bed cover is best if you want a really huge trunk.

On mileage, a programmer will help. Otherwise the CAI and Exhaust aren't really doing much for you. They might do all right, but to unlock the performance you have to get the programmer. Many programmers have MPG tunes.

@Maddog: Yeah the only way you can get around that is a driver mod.

Can anyone recommend a programmer for a 2003 Ram 1500 4.7L? I was not able to find one at DiabloSport.

while the 4.7 may be a good motor...you have to remember big truck + little motor = not a lot of mpgs...that's a lot of weight you are moving around
