Pro-Solo is a different animal than a regular (or National Tour) autocross. Its more formal and has a more rigid structure. That tends to get the competitors a bit uptight until they have done a few events. The whole Christmas tree thing kinds freaks out people who have never drag raced before.
I was at the El Toro Pro a couple months ago (just walking around, not competing) and my normal autox buddies who were at their first Pro were basic pricks until they finished their runs.
The Talon (and Mitsu GSX) folks have a chip on their shoulders when it comes to Pro Solo. Their cars can launch really hard and were the overdogs against the Camaro/Mustang ESP crowd until some rule "clarifications" pretty much killed their turbo engines. IMHO these clarifications were chicken s*** and were done to placate the pony car contingent. SCCA has no clue on how to classify turbo (and rotary) cars so they react with draconian measures.
