[FINESPLINE]

I had read a few years ago in a engineering journal that in many instances ( not all -but most ) that engines ( stock type ) can ran faster on a certain tune with lower octane than available race gas. That going as low as you can with octane with no detonation has shown those results. Would love to post the article but can't find the magazine since I moved. This probably has something to do with the big power engine builders and tuners are getting from pump gas motors nowadays. Wouldn't that be a nice shot in the wallet.
