Is 93 Octane worth the cost for towing?

[endoracing]

I apologize if this has been asked but I tried searching and couldn't find anything.

I just tried the canned 93 octane performance tune and it has been working really well. I am wondering if there is enough of a performance gain in a custom tune between 87 octane and 93 octane to get a 93 custom towing tune.

I have the 4.6L engine and we have a 26 ft camper that weighs around 5000 lbs. I also carry a motorcycle, generator, gas cans and some other track goodies in the bed sometimes while towing so overall weight gets up there a bit (but still within the gross axle weights). The 4.6L leaves a bit to be desired in the power area so I am looking for any increase I can get. I have been using the canned 87 tow tune as a daily driver as well as towing until I figure out what custom ones I want.

My thoughts are to get a custom 87 performance for a daily driver with fuel efficiency in mind. Then also a custom 93 tow tune and keep the stock 87 tow tune. Then possibly down the road get a custom 87 tow tune if I decide that I want to be able to run 87 and the canned isn't cutting it. For now if the extra couple bucks per tank will allow my truck to pull better it would be well worth it to me.

So that is the background, my overall question would be is 93 octane worth the extra fuel cost when properly tuned for it? In terms of towing power but I guess also would it help with efficiency at all?

Love the programer so far, Thanks!
