OE ECU tune on 91 octane
Is anyone using 91 octane with the OE stage 1 tune on a C43? I'm curious if it's a really noticeable difference over stock. I live in CA and only have access to 91 octane. Any feedback is appreciated!

Also, these are "off the shelf" (OTS) tunes. The difference in 2 octane points isn't going to be anything of consequences as these tunes aren't taking full advantage of the better fuel. I doubt any significant parameters such as ignition timing are changed via the ECU's automatic adaptive capabilities.
But I'm just guessing here so...
