Yep, your home region's
PCA DE at Heartland Park in Topeka - only about 4 or5 other Caymans there, but a good time for those of us who couldn't make it to Croctoberfest.

I don't know if it really made a difference or not - it's my understanding that the CS engine is optimally tuned for 93 Octane, and the best you can usually get in Kansas is 91 Octane. I don't know that much about how the Porsche engine management works to know whether or not it could detect that much difference, I just decided that I wanted to make sure I wasn't losing anything.
So, I added 5 gal of race gas to about 1/2 tank of the usual 91 oct. to make sure I was over 93 octane. Maybe someone more knowledgable about engine management systems can tell us if I was just wasting my money.
