Can Towing Tune be Left in Edge EvoHT2 part # EP86040 at All Times


If going from towing a trailer to not towing a trailer how critical is it to change the tune from towing to 87 octane.


Expert Reply:

As long as the fuel octane minimum is always met with the tunes you have loaded with the Edge EvoHT2 part # EP86040 there's no reason you'd ever HAVE to switch at any point. So if you like the way the truck runs and performs with the towing tune there's no reason you couldn't leave that tune loaded all the time.
