I see all the comments on better performance but I would like to ask what has the Cobra tuner done to your fuel mileage?

At first I noticed that it dropped from around 40 to 36 or so. But that may have been due to me twisting the throttle harder because of the performance gain. Since then my mpg have come up to average around 37. But the reduced heat and smoother engine operations are worth the small drop in mpg in my opinion.

43 mpg Riding 2 up, so I'm not twisting that hard. Solo is about 41 mpg, less weight but more aggressive riding.

I dont know but I know that the upper gear roll off is much more crisp. No issue- possibly a subtle change. I do know my gas useag hasnt changed significantly

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.

Very little but added life to motor since it is now running a better AFR. I am not to concerned about mileage I like the performance gains though

On my 2012 HD Road King, with Stage1 (Heavy Breather intake with 4" Rinehart pipes), the gas mileage improved slightly. But I down already from the estimated 42mpg to about 38-40mpg with the stage 1 kit. I noticed only an extra mile per gallon if any. But also, since the bike ended up with more low-end torque, I had a tendency of cranking the throttle up at lower RPM which is harder on gas. You won't regret the performance increase. More Torque, and much smoother throughout the power band.

You will sacrafice fuel milage, mine went from 42 mpg to 38 mpg. But worth it to me. I've made mods to the engine and changed exhaust 2 or 3 times and the Auto-tune keeps it running at peak performance. No more costly dyno after mods!

Will loose about 4 mpg but bikes come lean from factory so it makes it run richer and cooler. Better for ur motor in the long run. Friend me on Facebook . David dabeast laws

I have only seen slight improvement not mpg, maybe 3-4 mpg more. The big improvement comes from horse power and torque.

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

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

lol maybe like 1 mpg avg . another thing is lost bottom end power but gained mid -high. I guess its got something to do with how the comp is programmed for stock intake diff air /fuel mix. im goin to try programmer to see if mpg improves.

I went from 10mpg to 17 after using it. 2008 jk on 35's and 3.73 gears. 150-170 miles a tank to 250-280 miles per tank.

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.

the literature says it does but I've never used it. I have only used the first two programs the economy ant the number 2 for towing. I noticed a slight increase in power but not better fuel mileage in economy although I haven't been able to take trip to road test it, I've just driven it back and forth to work in winter using fuel to warm it up (I live in North Idaho). The tow program gives significant increase in power and fuel is still the same. I average about 15 empty hand calculated. I haven't tried the performance program yet I'm still playing with it.

Not much In mpg, power is increased. I gained 1-2 mpg with the 93 octane tune and it woke the truck up as well. Good luck!

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

At any given time 85% of my driving is city and I get 18.5-19 mpg. This has been consistent since I've installed the intake. I don't have a before/after comparison because it was installed only a few days after the purchase of the vehicle.

I returned my truck to factory settings passed emissions w\o a problem and then returned it to the high performance settings. Its quick and easy. I didn't want to chance taking the test with altered settings.

The performance is amazing in my truck a Duramax diesel, it keeps making power the more you push on the pedal! I keep mine on the performance setting and I love to feel it and hear it when I take off so it hasn't helped my fuel mileage, but I think it would if you drive normal.

What specifically are you looking to improve. I set my vehicle to the highest octane available so I use the 91 octane tune. I believe the I1000 also come comes with pre made tunes for each vehicle.

Yes my gas mileage increased 3.5 mpg at a the minimum. I probably would have gotten more but I have a heavy foot. I just sold my truck a couple weeks ago and no longer have any use for the superchip. If you want to purchase mine just let me know.... It's in perfect condition.

In my experience with a 2006 vic I saw a 2+ increase in mileage per gallon. But only after I stoped playing with the throttle.

Hi Mark,I've had this for 6 months now, I drive pretty fast all the time and haven't noticed much of a difference with fuel efficiency, but you can feel a difference in the power, and the sound is great.
