    Tow/Haul mode MM3

    So I recently did the @DRD Spark plug deletes on my truck and have a couple questions in regards to the tuner.

    I haul a 20 foot enclosed and a 30-foot gooseneck regularly.

    Does the tow/haul setting located near the exhaust brake button still do anything in regards to towing or should i just put it in tow tune and call it a day.

    Tow haul mode still works and changes the transmission shift schedule at bit.

    So feel free to use it if you wish.

    Biggest difference I notice is the exhaust brake function - much stronger than out of tow haul.

    For anyone else searching for this.

    Finally had a truly kinda heavy load today about 120 miles round trip and about 10k pounds both ways.

    On the way there didnt have it in tow haul just the DRD 30HP tune and exhaust brake on.

    Definitely was down shifting and all on the back roads for the brake but no where near as strong and hard on the way back.

    Barely had to touch the brakes until about 25MPH.

    And....shes doing the same trip one more time tomorrow.
