Nice update. I haven't checked in for a while and you have come a long way with the car. It is truly a work of art with great attention to detail. Bravo!
I found your dyno chart interesting as well. That nearly vertical torque curve from 3.5k-4.3K must feel like getting hit with a hammer.
If you bring the car back to Fontana for the Festival of Speed in April, as a very experienced Boxster driver on the Roval I would be willing to offer my services and act as test pilot for a few sessions... Purely in the interest of gathering data of course.
