Maybe it's just me, but I swear the Boxster pulls harder when running on more than 91 octane.

I thought Ethanol was a big concern so I'm only using Shell Vpower 91 (only non ethanol in Canada) and adding STP octane boost per tank ...

I do the same. Shell is the only one (I am aware of) who doesn't have ethanol in their top octane product. I give it a shot of the octane boost per tank as well, it seems to like that.
