Any improvement on gas mileage with this intake?

The intake itself will allow air to flow to the turbo much quicker and allows the trubo to breathe easily at the top end of the power band. This helps throttle response and gets the air to the turbo much better than the stock baffled intake. The hard piping adds a nice amount of noise to your intake, it also makes the bypass valve very audible. The improvement in fuel mileage will come more from a tune than the intake itself. In order to maximize performance a tune is recommended but it is not required.

No. Keep in mind if you buy one of these you HAVE to tune your car, or you will be damaging it. There is no off the shelf map for this intake from cobb (access port) so you will have to get a custom tune.

I have not noticed any impact on gas mileage, however I drive like an idiot.

I have seen at least a couple more mpg, using this and TP stage 1, open-source.

I have a 2000 ls 4x4 and I noticed no improvement with hp or mpg, however it was a nice replacement for the cheap autozone intake I bought the truck with. And it makes the engine bay look very clean, took about 1 hour to put in and was really easy. I would recommend this intake over any other unless you still have your facory box

The HP gains are minimal with just the intake. It sounds a little tougher, runs a little smoother. Once you get started on the MODS you put something on you need something to compliment it for it to work. This intake brings a lot more air in so you will need an upgrade in the exhaust, stock pipes won't let as much out. If you have updated your exhaust you will see up to 20 ponies added!Will also make you sound like a true muscle car. I did both on my RT and very happy but not satisfied. Now have the next upgrade to compliment these two upgrades! Hope that helps. Good luck. Have fun

I have had this programmer on my '96 7.3 for four years. Never a problem, and it does improve the performance . I haven't noticed any better fuel mileage, but it does improve shift points when towing. I wouldn't recommend using it on the higher settings without a full set of gauges -- EGT, Boost, and Transmission temp at a minimum. I put in an extra transmission cooler just to be safe. Running at higher power settings puts extra stress on the engine and tranny and makes things run hotter. Running synthetics will also help keep the heat down.

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!! it is a tremendous gas saver and really helps when you install it into a cold air intake! more horsepower for my vehicle

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.

yes.. it made a 2.5 mile per gallon difference when pulling (5000 lb trailer) saw some increace when not pulling 0.5-1.0 mpg. I also used a high flow air filter with it.. no downloads

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.

Flow rate is higher but I used these on my 1986 it now runs better than ever. The computor will adjust itself. In my opinion way better than factory injectors.

You may get 1 or 2 mpg better but its not a guarantee. Mostly depends on how you drive, how long and often you idle the truck and also fuel quality.

I honestly think that the stock tune gives you better mpg than the fuel saver tune. An you can run any gas. It gives you the octane suggestions for whatever tune you set it on

MPG down a bit but better since adjusting. Imstalled on 72 ghia. 1600 stock engine. The boost in performance is massive.

LisaI bought the tuner to go on a 2006 Chevy 3500 Express van. I pull a 30ft car trailer with it. I have had it for a month or two. I have seen a gas mileage improvement of 2 to 3 miles/gal. Which I drive long distances. It does improve the power and fuel economy. If you drive a lot a mile or two per gal is a great help.

I installed the cat-back and intake on the same day so it might be different with only the intake but I noticed a 2-3 mpg gain after I got over getting into it all the time cause it sounds so good.

I didnt see much mpg gains! Maybe 1mpg! There is several different tunes 89 octane and 91 depending what u want!

I did notice a difference, especially pulling the 5th wheel camper. I went from about 8 mpg to 15 mpg with my 6.0 HD
