no problems with my 12.6:1 compression ratio on 93 as of yet
but due to autox'ing in the Florida heat, i've opted to head over to Sunoco on Dale Mabry by Waters and go for the 100 octane
Amazing how it has stayed at $5.99 per gallon all summer long. I only drive the car for events so I don't mind filling it up.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
