I'm looking for a little knowledge on Octane rating. I have a Gen 5 6.2L with a whipple supercharger and a custom ground cam. There is some question to what octane level the fuel tables were made for. It is either programmed at 93 (as I requested) or 91 (sticker put on the fuel door).
My supplier of 94 octane is no longer going to be selling high octane fuel. How can I tell by monitoring if 91 octane is safe for the timing/fuel tables written?
Will there be certain codes set? Or extreme retarding of timing?
High octane fuel is hard to come by in Oklahoma, but every station in Texas and Arkansas have 93 Octane.
Thank you for any insight
Jack.
