Finally for my beautiful 2022 Longhorn 1500. But with gas going up to $5/Gallon, I need to try to help the fuel efficiency and looking to ad some mods but could use advice.

Heard performance intake and performance exhaust would help with this.

Also thinking of adding the Pedal Max by JMS to eliminate the delayed in transmission response when hitting the gas. (this is because of the delayed reaction when hitting the gas due to electronics but I might be wrong as to why it lags).

Any advice is appreciated. That ks on advance IMG_0791.jpg

Crunch some numbers. See how many miles you'll need to drive to recoup the expense of the new exhaust. I suspect the gas will be cheaper.

A Borla cat back system is over $1000. Let's say you're getting 17 mpg at $5.00/gallon. 29.4¢ per mile in fuel. And we'll be optimists and say you are able to restrain yourself from hearing your exhaust roar and that this new free flowing exhaust gains you 2 mpg. 26.3¢ per mile. That's 3.1¢ improvement. $1000.00/.031 = 32,258 miles to recoup the expense. If the exhaust costs more than a flat thousand bucks, it will take longer. If you don't gain 2 miles per gallon in fuel economy it will take longer. Maybe it only adds 1 mpg. Then it will take almost 65,000 miles! And if you aren't able to control your right foot, it will take longer. Possibly never.

You will see the most improvement in fuel economy by adjusting the nut behind the steering wheel. https://fueleconomy.gov/feg/driveHabits.jsp

Intake and exhaust will give you nothing. This isn't 15 years ago when the factory installed restrictive components. The current intake and exhaust are as good as most aftermarket ones unless you go for a performance tune.

The best thing you can do is not spend money to save money, so get aftermarket parts out of your mind. Next, watch the movie "Driving Ms. Daisy". Adopt that driving style and mpg will certainly go up.

If you feel the need to make your wallet lighter in the attempt of saving $20 or $40 per month on gas, then look at low rolling resistance tires for a set of aluminum or steel 18" wheels (whichever is lighter). The lowest rolling resistance and lightweight tire (paired with a lightweight wheel) will net you the greatest gains through reducing unsprung weight.

Before you jump on a performance intake and exhaust you need to find out what cubic air volume the engine requires and then match the intake and exhaust to match the engine's airflow. But wait, the stock intake and exhaust already do that. So, air intake is eye candy, the exhaust is ear candy, and both drain your finical resources.

Any device that removes the mushy pedal response is most likely going to reduce your MPG because it invites harder acceleration. The reason the accelerator is mushy is to give a bump in the MPG by discouraging jackrabbit launches and other poor accelerator behaviors.

Nothing you add will improve mpg enough to justify the cost.

You’re left foot and driving below 65mph is all you can do to keep the mpg numbers as advertised.

So true.
Although I do not have a CAI installed, the Flowmaster muffler I installed really had an opposite effect. I just wanted to lean in to it because it sounds so good when I do.
I gained around 2-3 mpg's by NOT leaning into it as much. With my daily commute, that is a huge gain by just adjusting my daily driving habits a bit.
Other things like, not idling for long periods of time, or hard takeoffs from a stop, etc.
The 5.7 is a thirsty SOB. Need to learn how to limit its intake, that's all.
For me, adjusting the idiot behind the wheel was my biggest mpg gain mod to date. :)

Your left foot is definitely the best money saver because it never touches the gas pedal. 🤣

Like everyone else has said, no mods. If you do even see a gain you're looking at potentially years to recoup the cost.

Best thing? Keep it below 70, or 65 if you can stand it. I say this in every MPG thread that pops up once or twice a week and is easily searchable, but if I'm on the interstate driving 75 I see about 16 MPG's in my Rebel. If I'm driving my kids to daycare on a 4 lane highway doing 55-60 I see 19 MPG. Avoid routes that have more red lights. Starting from a stop is a HUGE pull on gas.

To piggy back off of that, on the road that I normally take if I do 65 mds will kick on for most of that road, if I push it to 70, no mds. Idk if that's how the system is programmed to work or the road that I'm driving, but mds being on is always better for mpg.

We all bought trucks for whatever reason we wanted to buy them. I wouldn't know how to act without one! Trucks are not famous for getting good gas mileage, even within the truck world. No looking back now. I think they are built as well as can be expected for gas efficiency. At the end of the day it's still a truck aaannnddd the very next morning it's still a truck, thank goodness.

As already mentioned, drive it easy, light right foot. Keep the tires properly inflated. Avoid oversized tires for the near future. Clean the air filter. Keep it below 2000 RPM, except on the very rare special occasions. Coast into the stop signs, let MDS do what it can. We are coming into the summer blend of gas, that will help a little bit. Just use your head and keep truckin!

Watch your speed, and how heavy your right foot is, that's about all you can do.

Pulsar on economy mode netted me a 1-2mpg increase in gas mileage. I wouldn't pay full price for one, so watch for people selling them used.

Could also lower the truck. Reducing ground clearance helps aerodynamics.

Keep speeds lower. Drive speed limit instead of going 5 over.

I have noticed a positive change when doing this. I drive the rural two lane roads to work, dropped my speed from 60 to 55, and there was an improvement, not that I'm complaining about the mpg though.

Makes sense. So lowering the truck height will help. Good note. Wonder if it's a big job to lower the truck.
