Valley Racing in Beecher.
If you are familiar with the biker bar Sollit, he very close to it.
Speak to Brian Conley.
He tunes with everything out there, but I got the impression that he prefers the SERT. I'm sure he's either leaving soon, or already left for the Gainesville AHDRA race, so you might have to get with him after the race.
He's about a half block off Illinois 1.
