Looking for Dyno experience in No. IL

[REO Scorpio]

My goal for the summer is to finally get my bike tuned. I've been running a PCV and Autotune for two seasons and don't feel I'm able to get the best map possible.

Has anyone had their bike tuned by a shop in/near Northern Illinois?

I'm in the SW suburbs of Chi-Town.

Thanks in advance for any replies.
