How much of a difference in mpg after installing the hitch, if any?

It is completely concealed within the rear bumper. If you're insinuating that there is drag as a result of installing this, which would decrease mileage, that has not been observed. This should be the absolute least concern. The hitch is great!

No. Still getting 35mpg highway 27.7 mpg overall. Same as before the hitch.

I went from 15 avg to about 17.5. I do tow a lot, so that included highway, city, and towing. My best road trip unloaded was 18.35. But I ran the transmission tune as well, and setting on HOT!! Great power when you need it! Running with DPF removed is a must to gain any real mileage.

I used this in a stock 2006 f250 v10. It seemed as though I got some power increase, but I didn't notice any significant change in mpg.

I have a 2010 JK with cold air intake and larger tires and it did make a noticeable difference. The shift points have changed and at freeway speeds I am not having to floor it to make it up some hills. The throttle response has improved too, not a kick in the pants difference but one that you can tell. As for mileage, I measured it for 3 weeks before I programmed and I was getting about 17.1 mpg after the tune I was getting 19.3 mpg. I drove it the exact same so I can say with 100% clarity that for me it did improve the mileage.

Your lucky, I only get 11.2 mpg. I haven't tried the performance programming yet. I am only using the tire size setting for my FX4. Let me know what you get for mileage.

No, the hitch should not be in the way. This is basically a replacement muffler that occupies the same space as the stock muffler.

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!

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

I have noticed no difference between the Supertop and the tonneau cover I had on prior. However I noticed a 3+ mpg bump when I added the tonneau. If you have nothing on now adding the Supertop will reduce tailgate drag without adding a lot of weight. I would assume you will see a similar 3+ mpg bump.

I noticed no major difference in gas mileage. In my opinion taking the faring off would increase the wind resistance. The larger factor would be the load in the rack.

Not sure about the 4.7 . We put it on a 2003 Dodge diesel and we gained about 4 mpg.

I have noticed no significant change either way. Aerodynamically seems to make no change; it's so light there is no affect by weight. (I have the 6-cyl Tacoma.) If there are any worries about MPG when there is nothing in the bed it can be folded up and I would bet it makes such a slight presence as to have no effect on MPG whatsoever.

Sorry, but I returned the item because I did not notice any difference w/ my mpg's. I also had and returned the k&n intake system. Both were installed at the same time and taken off at the same time. Hemi's are just horrible on gas!!!

Mine is on a 2001 Jeep Cherokee and it never got good gas mileage without the rack. Have the fairing on and have not noticed any drop in mpg. However I only drive this jeep off road for fun and not daily.

There is no horsepower gain if you just add an air intake. You will feel a much better throttle response and I did gain about 0.7 mpg. Very easy to install, highly recommended!

I have an 09 dodge ram quad cab with 5.9 hemi. I bought the 3840. Money well spent if you are looking for more power!!! Just make sure you know what you are doing when you go to advance settings!! Don't take for granted that the numbers that show up are right! You will need to look up your spec's and make sure you got it right before down loading the program. I wrote down my specs in the book that came with it. I use the 87 setting the most. You will notice a difference from stock to 87, 91, 93!!! Fuel mileage goes down about 1-2 miles per gal per step up from 87. Hope I helped.

Dusty, I can't tell you how much of an improvement it was because I hadn't really kept track prior to the conversion. However, I did take a trip from Oregon to Yellowstone and then down to Colorado this summer in my fully loaded down 3/4 ton suburban with a 5.7L V8. I am not a slow driver either. I typically do 75 to 80mph on the freeways and backroads. Anyway, I averaged 14mpg which I was pretty happy with considering the weight of luggage and a larger family. Hope that helps!
