I have 3 tunes
Octane 87
Octane 91
Octane 93

I tow a mower everyday so does that mean I run the octane 87?
I also noticed running the octane 87 it shifts a little harder. Is that normal?

Did these tunes come with your SCT by SCT or are they custom third party tunes uploaded on your SCT? I have an SCT x4 that I used on my 6.0 diesel and am thinking of paying to have it unpaired and updated. I didn't know whether or not they wrote any tunes yet.

Also you should run the tune based on what gas you put in your truck.

@njrucci If those are the default tunes that came with the SCT unit, they are rather generic performance tunes and would not get you the same gains as a custom tune. For example, 5 Star Tuning has multiple towing specific tunes available that would be better suited for this than the default ones. Also you can try just running 93 Octane for a week or two before flashing it. It's well documented that the 2.3 Eco engines sees a nice bump in HP and Torque from that alone and may be enough for your needs. If not then I'd recommend a towing specific tune based on the type of fuel you normally run.

This.

Also not sure if a mower is heavy enough to warrant a towing tune.
Depends on the mower. Some of those zero turn mowers weigh in at around 650 pounds and another 700 for the trailer. So running a towing tune might help.
