Default Any dyno # changes between 87-93octane tune??

5.3L boltons, cam, tuned for 87 octane. It's around 20-22 degrees of timing shity ethanol in the gas

Would it be worth my time and money to get it retuned for 93??

Any body dynoed the difference?

I know, I know, I know it is only $5-10 more for premium haha, but when I fill up 2 or 3 times a weak it would be an average of $20 more a week times 50 weeks that's an extra grand a year on fuel.

I wouldn't mind paying that money if there was mpg and pretty significant power to be gained
