First Rumblbe I don't feel I have a bad tune and have had no bad experiences. That's why I asked what goes on at a Dyno Day. It's good that it turns out to be a get together B/S day I'm down for that. Was worried some guy everyone thinks is a great tuner would miss my tune up and as it turns out I don't have to worry about that.
I've been to a lot of Camaro functions but never a Dyno Day so that's why I asked. Didn't mean to sound negative and I want to thank the members who provided the great answers to my question n the rest "it is what it is"
Have a Sparkly Dyno day n happy motoring.
