Anyone used a shop to have their Q-jet, or any other carb for that matter, tuned? I was looking at the yellowpages and saw EPS Inc-Chip & Walt Hane. Apparently they use a chasis dyno to tune carbs. There was also Vern's Carburetor Service that specializes in GM carbs. I was looking at Dyno Pro's website and saw a lot of cars tuned by Golden West Performance. Anyone have experience with any of these? Or any other place.
