I finally got my predator up and running. Question, I can't find any 93 octane fuel near me, however, there is 92 octane literally around the corner AND is the cheapest premium gas within a few miles. I ran both the 91 and 93 tune, must say, the 93 was way more impressive, especially when it comes to throttle response. Any harm running the 93 tune w/ 92 octane fuel?

as long as there is no Knock with the 93 tune, its fine.

Sorry, no one seems to want to explain. I don't know how to tell if the car is having knock. Can you elaborate a little? Thanks in advance.

Well.. If you did your data logging to adjust your fuel trims (LTFT`s) and such, the knock (KR) is one of the parameters required to log.
What Vehicle are we talking about? There are different parameters for different manufactures!
