2014-2021 Chevrolet Silverado/GMC Sierra Top Ways To Increase Fuel Efficiency - Phastek Trucks

Please tell me you did not just recommend a throttle body spacer? I can agree with all except that because there is hardly no benfrom a throttle body spacer.

[@ridin2low4u]

I’d really like to see a comparison of all this added to a truck versus all stock. I bet it doesn’t improve it +1 mpg in real life with same driving habits

[@chrisweaver2143]

No if you upgrade all those parts you will def get around 1-2 mpgs . Raising the tire pressure alone will give you a small gain .

[@johnnynguyen9449]

@@chrisweaver2143 went from 22mpg- 25mpg on highway with tires on 37 psi vs 34-35psi

True story

[@wildone1480]

What tire size and offset? It looks good!

[@PhastekTrucks]

The wheels are 20x12 with a -44 offset. The tires are 33x12.50

Can you provide a link or more info on the range afm. I’d like to learn more. And purchase one.

Does the AFM void the manufacturer warranty?

[@PhastekTrucks]

No it should not void the warranty. It is easy to install, and to uninstall. But if you're worried, we suggest you ask your dealership.

[@seangowan7441]

Will the range afm+ module drain the battery with the truck off?

[@PhastekTrucks]

No. This should not drain the battery.

[@chrisweaver2143]

I have one in my 2015 5.3 LTz silverado . I leave it in all the time and it does not affect my battery at all . I actually get better mpg with it . Not much , it does drive better . Not as sluggish when it would normally be in v4 mode . The real reason I keep it is because it will minimize oil consumption throughout the life of the engine and prolong my engine. But they work wonderful

I installed a Cold Air Inductions Cold Air intake and a throttle body spacer that I got from American Truck and actually saw my gas mileage go DOWN by 3 mpg. I used to get 18mpg( over sized tires and a muffler delete) on my 2021 Silverado. Now, I get 14-15 mpg with the same driving habits. Could I have installed wrong?

[@txkingg]

i hate how they say Cold air intakes help, that has never been proven. i don't think you installed it wrong, but more air in the cylinder might require more gas as well

[@Chevygirl26]

Is that stock height

[@jasoncook9269]

I have done all that!! And it did not help at all!!!!😂

[@vernwhite568]

He forgot plugs and wires to !!!!! And exhaust leaks

[@ri0t-alex0clan17]

Change the grill

[@nicholaslugo9118]

😂 what a joke this video is , the spacer will not increase gas mileage, also. So of those cold air intakes are actually more restrictive than the factory filter ! The only thing that matters s actual is making sure ur tire pressure is correct
