In today's engines with mass air sensors, you get more fuel with more air. So how can you get better mpg?

I can't give you the perfect answer but my mpg went up about 1.5 in the city and about 2.5 to 3 on the high way and the truck has more throttle reponse

i got this to (hopefully) improve my low to mid throttle response, marginally noticeable.

Yes, you will use a little more gas but it all depends on how heavy your foot is. I find that it has more pickup so I can usually keep my foot off the accelerator so the trade off of power to mileage is not that bad.

Changing to this EFI system will remove the leaks causing the gas smell. Additionally, you will see fast starts, better throttle response, increased power, and better fuel efficiency. We have it in stock and ready to ship. Thanks!

Actually, the higher the octane, the slower and cooler the fuel burns. That's why you have few knocks and your Harley will run much cooler and more efficient with 100 octane fuel. They sell Sunoco race fuel here in CA that is 101 octane and my FLHRSE runs great on it. Some guys take a 5 gallon gas can to the airport and mix avgas with super.

I got about 1-2 mpg extra on the performance tune... with a gentle right foot. Heavy right foot... not so much of a gain!

My car uses premium gas but this does more for your car for cleaning etc. Gas choice just affects some performance but this would be for additional cleaning & performance.

No. It is a passive system that monitors your vehicle's performance. But, it can show you how to modify your behavior to improve fuel economy.

In lame terms, it is explosiveness of the gas. Higher octane value produces higher engine power.

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

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

Try to avoid ethanol in your motor. According to my local small engine repair shop, fuel with ethanol tends to congeal quicker than regular fuel.

Use a upgraded plate and pump. It will help the life of your engine & keep your engine running quite a bit cooler. Crank run out was checked with a special dial indicator.

Yes. Your MPG will increase and you will feel the difference in acceleration.

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

You use just regular gas, don't forget to fill it with oil before starting. And don't overfill the oil, its worse than under filled. Use 30 wt oil, any brand!

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.

Im-friggin-possible! Who put two cycle fuel in the gas tank? To my knowledge the only way oil gets into gas is if you have a multi cylinder engine and one of the spark plugs is not firing.
