Let's talk octane...

When you're switching from one octane to another, you need to siphon out all of the previous fluid correct? Mixing the two = vewwy bad??

not necessarily. Of course, running your high octane tune and getting a load of 93 into the engine can be risky.

I ran mixes of C16 and pump gas with no issues.

With that being said, is there say a noticeable difference you could sense that you knew it was time to switch from say a 93 octane map to the racing fuel octane map or vis versa?

some fuel formulations don't blend well together. And running the aggressive map when it's not suitable puts you at risk of detonation.

On my car, it wouldn;t run on 93 with the c16 map.
