i get good fuel mileage now but would love to have better will this system do that?

On the economy setting expect 1-2 mpg gain. I run the tow setting and get the same fuel economy as stock with much more throttle response. Take into account I have an 07 3500, 5.9, 6 speed manual

Yes it will help your five nine get better fuel eco. And a little more power depending on setting.. 40hp. 70hp. 100hp great for the price!!!

I have a 2011 Eco boost with with volant air intake. I have consistently got 2 MPG better, than without.

Gas mileage didn't really change but it does seem to have more power. More in throttle response than anything.

if there is a better chip, I'm not aware of it . I have a 2500hd with a 6.0 L gas motor, K&N air box and filter. I programmed the chip for Towing. It definitely added Throttle response. But I can't say Ive noticed any mileage improvements. With the performance enhancements I think I drive the Truck a little harder. Also the chip requires premium fuel. Bottom Line if your trying to save money on fuel you'll probably be disappointed.

Great questions. We see an average increase of 33% in fuel injected vehicles. You can send me your current fuel economy and I will calculate this savings for you if you like. These kits reduce your emissions to almost zero.

I use it on a 2006 Chevrolet Silverado Quad Cab 4x4 Z71 5.3 and my fuel economy get increased on about 15% on regular fuel.

Overall my mileage dropped about the same amount ~15% that the performance increased according to the run on the dyno after the installation. I put a new higher flowing air cleaner, and exhaust system at the same time. Most of the decrease mileage is caused by me using the extra power. If I cruise gently, I get close to the same mileage. There should be a slight decrease from the fact that H-D runs the engine leaner than what is good practice for keeping the engine from overheating. At least that is the story that I have been told by several people. The Cobra tends to add a bit more fuel to the mix which is probably worse for emissions and mileage, but better for engine life.

I did a few things all at once, adding the Airaid was one of them along with cat. back exhaust system. I do get a little better gas mileage, I have less low in torque but more top end. I am happy with it overall, it did change the sound of the car a little. I don't know if this helped at all

Yes. Thats what i drive. I did the fuel saver tune and get roughly another 2 mpg. But I also have an intake, throttle body spacer, and an exhaust. So instead of the stock 18 mpg highway im at 23 mpg.

Yes, I am getting 1 or 2 mpg better than without it. For an upgrade this well priced, you can't go wrong really.

If you have increased Tire size it will also take away some Torque, but yes, this will most certainly increase performance. Remember to reset it back to towing mode if you are towing it also has a performance mode, plus a fuel economy mode, i do like mine it does make a difference also a K&N; cold air intake will help improve your performance as well.

I could see no noticeable MPG change when using this box. I consistently take 400 mile trips and have done so with and without the box. MPG seem to stay within my avg total over several trips.

That doesn't sound right. I'd double check the vent tube and oxygen sensor. At the very worst you would not lose mpg, only gain hp.

I have been installing air intake systems and exhaust systems to all of my vehicles for 20 plus years. The combination of the two does increase hp and torque as well as fuel mileage. The fuel mileage can only be realized if you keep your got out of the new hp. Lol. Yes this system does add hp. Simple to install s well. I hope this helps.

Check the size of the fuel line. If it fits the line it should provide sufficient fuel flow. I ad a cutoff valve on the line above the filter and run the gas off the filter and carb.

Yes! and make sure you have to check your carb. fuel sometime old fuel makes it worse.

Mileage seems to be the best on the "Street" tune, hand calculated. Changing from "Stock" makes the computer think it's using less fuel than it is. Usually burning about 1/2 gallon more per tank than my computer says I am, resulting in less mpg than the computer tells me.The tuner isn't the only factor in determining mileage. Removing the DPF, adding a CAI and blocking the EGR has a little to do each. I average 17mpg city-ish... and on a 65mph highway, early 20's. Like 22mpg. Conditions are never the same for anyone though. You will see a slight increase, but nothing crazy. Again... too many variables to include.
