A flex fuel kit should allow the tune to be optimized for any fuel quality. The OFT is less flexible than Ecutek with custom maps. You can look up Ztan’s flex fuel work that was ported to OFT and decide whether or not that works for you.
I finally bit the bullet and purchased a delicious mk1+ flex fuel kit and Ecutek from HRI Tuning. The flex fuel kit is easy to install. I’m using HRI for the tune because of overwhelmingly positive customer feedback and unlocked tunes. I’ll post here to let you know the difference in how it drives if any once the tune is complete.

Why couldn't you just make a summer tune for better than e60? Also, it has been explained that there REALLY isn't any real gains to be had over e60.
The amount of additional timing you can run is negligible.
