So how bad is it getting hold of good fuel over the pond? In the UK we can get 97RON or even 100RON at pretty much all filling stations. It's working out great at the moment, as our fuel is mostly TAX and as that goes up the cost difference between say 93 and 100 is getting really small.
Also, in reference to the original post, are you aware that the twinspark motronic already has map switching for different fuel grades, its a 'relay' plug (looks like a relay, but its actually just a jumper cable in a box) under the dash. Check craig's site for info on how to set the fuel quality; in essence, you could run it set for 91RON on the road for economy, then use a jumper to set it to 97RON+, stick in some premium and head for the track, although the settings will not be as aggressive as say a chip change
