No, I'm sorry but I don't. I live in the sticks in southern Indiana, about 100 miles from anywhere. But I'm sure there are plenty of them around the burb's of Chicago, I believe there are several members near the Chicago area, maybe one of those guy's will chime in. Actually there is a good dyno tuner that lives right behind me, but you would have to pull your engine. He builds race engines, let me rephrase that, he builds monsters. He's one of the best engine builder's around, people come from several states away for him to do their engine's. I love it when he sets one up on his dyno to tune it in, I get MEGA GOOSE BUMPS.
