Stupid Question... 93 on a 87 economy file?

[11ESV]

Hey All, I bought my Predator about 5 years ago to turn off AFM and bump up the idle RPM on a 2011 Escalade ESV AWD (The Pig) I picked up. Ive been running the Diablo Tune ever since.
I was cleaning out the garage and found my predator in the box, decided to update it and thought, "Hey, your going on a road trip this weekend, why not see what the economy tune can do for your MPGs"
Im consistently 16.5 MPG running about 75-80 mph on road trips, just for shits and giggles I wanted to see if I could bump that up.

I have strictly run 93 since I got the truck, so the question is.....

Running 93, can I run the 87 Economy File? The Truck should adjust to the difference in octane correct?

I just Broke 140k and the motor is solid I just dont want to f-something up.

yes, you can always run more octane than the tune is rated for, just avoid running lower octane than the tune is designed for.
