Do you notice any mpg gain at cruising speed? And throttle response

You won't really notice the mpg gain but you do feel the gain in throttle response.

Improved sound under hard acceleration, initial improvement in MPG has since evolved into a decrease over stock air box. No improvement in throttle response......if I had to do it over again, I would just get a K&N; filter for the stock box.

Maybe a minor MPG increase but not enought to brag about. I think it depends on your cruising speeds. Most roads I travel are 60-70mph and get between 16-17.5 MPG. I receive 18-19MPG when traveling 45-55. I noticed a slightly improved response after installation but don't expect a race truck. The sound slightly improved...mostly from Borla Exhaust.

Better throttle response. Gas mileage goes down about three per gallon. You need to add the throttle spacer and possibly stainless steel dual exhaust for best performance.

It does add some power. But you have to have a turner. I put this product and a h&s; turner with dpf delete and throttle response and power are awesome. My turner is not turner up much either.

I have a 2012 F-150 Ecoboost with an AFE intake on it. I managed to pick up about 2 mpg on the highway with the SCT tune. That's the performance tune, not the economy one. In town, I haven't noticed much but I also have a heavy foot so I'm not surprised.I'd gauge your potential mileage based on your driving style. If you're in town and heavy on the pedal, it might actually get worse or just not improve. If you're doing more highway and you know how Cruise Control works, you will probably pick up a few MPG. A recent trip from Chicago to Michigan had me doing 22mpg, better than my truck has ever gotten before. That was with the cruise locked in at 75 most of the way, running 93 octane and the performance tune. I have a 2012 F-150 Ecoboost with an AFE intake on it.

It will fit very easily and nicely. It's difficult to gauge the MPG since I did a few mods (K&N; intake, Edge programmer, BBK throttle body, Accel COPs), but altogether on a trip from Alaska to Texas I averaged 19 MPG when I finished. Now I tow a lot on short distances and I get an average of 16-17 MPG.

On the highway, with the gas saving tune I gained a couple mpg. It does really good with premium fuel. In the city it's not that great. If you drive a lot of highway/freeway miles then it's worth it. I put dual flowmaster super 40s and a K&N; on it as well and if I drive right I can get 18+ mpg on the highway

As long as you keep your foot out of it and drive responsible there's a gain dependent on the vehicle. Otherwise it's about a two to three MPG loss hotroding around.

i really have not compared before and after. on the highway i average 26-27 mpg. i have really noticed a power increase and i just love the sound when i put my foot to the floor.

Didn't notice a drop in MPG. But do take note that the tires are taller than a regular tire the same size. When I turn corners it rubs really bad because I don't have a lift on my vehicle. Just FYI

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!

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.

My gas mileage definitely improved. More power and torque as wellI'm in canada so we measure in litres/100km. I went from 17-18 litres/100km down to 13-14 litres/100km. About 20-25% fuel savings. Biggest difference is in city driving and towing. They're are a lot of different models, make sure to get the right one for your tuck

Increasing throttle will increase speed, but not by much. Best to adjust so that the engine is not "screaming" and go with that. It will cultivate pretty decent at a lower speed, but you need to increase it to till.

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

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.

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.

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

As far as both questions go I can't give you an exact number on both gas mileage and horsepower. I did feel an increase in power since the intake does make the engine breathe a hell of a lot better. As far as gas mileage goes I did see an improvement but couldn't tell you how much as I didn't pay attention to that after I put it on. AS far as the intake itself. It sounds amazing.
