towing tuner

Hi everyone. I own a 2019 SR5 5.7 and its awesome but I feel like it could be more. Does anyone know of an all around system that will allow me switch from a "hauling mode" and a "gas saving mode"? Any help is appreciated. Thanks

 

Welcome to the forum, this seems like a joke? That’s what the Tow/haul button does??

 

whatever you do, don't try out the tow/haul mode for the first time in the rain or in traffic!

 

gas saving mode

in a Tundra?

 

Supercharger. Harrop or Magnuson.

Or long tube headers and a 93 octane tune.

Granny the gas pedal to save gas, foot down when towing.

 

There isn't really a "gas savings" mode. Use street tires and don't get any lift mods; stay under 65 MPH and avoid stop and go traffic; avoid carrying extra weight. You'll get the EPA numbers or fairly close.

You can try a throttle controller but bear in mind these don't change performance numbers just the throttle's responsiveness.

Outside of this you are looking at performance mods which will likely diminish your MPGs depending on how you drive.
