I read alot of reviews that said that when you just use the filter that it increases gas milage. Has anyone noticed a difference in mpg with this ?

I have definitely. Before the install I was averaging about 19 city and 26 highway. After I'm looking at right around 24 city and and 32 highway... about an extra 40+ miles per 15 gallons. ALSO better acceleration and easier cruising.

The company claim it will increase fuel mileage but my experience is bigger tires less fuel mileage the tries weigh more there for more work for the engine to turn them and also now you are geared a little higher sometimes that causes a drop in mileage. Another thing to consider before purchasing is elc device are hard to get reimbursed so if you are considering trying and if it dose not do what you want it to do retuning it that could be a problem unless there is something wrong with the devise.

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.

Gas mileage is possibly 1-2 mpg better. However, I mainly upgraded for improved performance, which is noticeable.

It gives you more air flow and it creates a cyclone effect. I put this onto my 95 Chevy with the 7.4L and went from 8mpg to 18mpg. I also added a split port and have 2 cone filters.

Anytime you increase horsepower in an engine you stand to abuse the tranny, rear-end, and tires along with everything else in the suspension. It really depends on your personal driving habits. If it's a Ford 7.3 you're driving, I saw a terrific increase in power with my 96 F350 with the 100 HP kick. A WHOLE LOT OF FUN. Would have liked to have seen better mileage but only have a single 4 inch exhaust out. My drive habits did not see an increase in mileage if not lost some. A friend of mine drives a 2001 or 2 Ford Exabition with this programmer and has increased his mileage 20-25%.

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..

On my 2004 Jeep Grand Cherokee V8. I only noticed trying to save gas mileage only got 1-2 MPG improvement. The shifting does great and really smooth. I have a K&N; intake and still no performance difference. Idling was a little smoother. I have not tried the high performance feature. Towing feature does great lots of torque. Hope this is helpful.

Katie you need to fill you gas tank and then add BG on top of that it will work its magic. You should notice the difference right away!

If I'm not mistaken I don't think that any where they say how much power you gain, it mite say on some forms from other customers if you want to look that far, for me I got it for my 6L 2500 and a air intake and noticed and good difference and I keep my set on meduim tune, I'm very happy with it, worth every Penny.

Perhaps I'm not the person to ask, I don't think they are worth the money, my experience, owning 3 of them and carefully tracking gas mileage before and after installing that they don't seem to have any effect on power or fuel economy. In the future I'll be sticking with regular old paper filters.

I have a 99 Silverado 1500 5.3L and i was getting 18 MPG. However i put a 6" lift with 35" tires on it. My MPG dropped down around 13. After i put the programmer on i usually get 15 MPG driving conservatively. However, after i perform a oil and oil filter change, and clean my K&N; air filter i will get a high 17 MPG for several fill ups then it starts dropping to 15.

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.

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

I live in a Chicago and I don't see any improvement in mpg in the city but on my trips to Detroit on the highway I might get 1 or 2 mpg improvement that I can notice. It was worth it regardless, makes the car sound better. Pair it with a decent exhaust system..even a pair of flow masters 40 or super 44 series and you will sound pretty good. I have this on a 13 2lt RScamaro and I get good compliments.

I noticed no difference in mpg or any hp changes. The old exhaust tip just was way to ugly for me. However the new exhaust tip looks so much better and gets the look I wanted!

Yes, you will notice a benefit in fuel mileage and a small benefit in performance. I've used K&N filters on every car I've owned for the last 20 yrs! You can't beat the price on Amazon for a drop-in filter.
