Has anyone used this mileage booster in their Tundra? I have one and am just not sure if it will void my warranty. 2019 5.7 liter.

Most mpg devIces fake the ecu into a AFM where the air is less dense. This creates a lean condition that results in higher exhaust temps. Besides the lower HP, the higher temps produce more polygon gases and can burn out your cats.

Your choice
