I was surprised recently when having the dealership work on getting everything dialed in right for a chevy crate engine I had them install. I have the Edelbrock Q-jet and it needed some adjustments. They say they can't do it. Although recently they did adjust the choke on it. I don't know it seemed odd to me. I went home and did it myself with tach and vacuum guage. I was hoping maybe they could do more with their fancy scopes and stuff. Dealerships are funny. Sometimes not that funny. Anybody else experience this?
