If you have never tuned a bow you might get that shop to help you out. Some times if you are not sure of what you are doing you can make things worse. If it wasnt so close to season I would say play around with the tune but as season is here I would get profesional help to insure you get it right and fast. Also spin test your broadheads and if they wobble at all chunkem. If no wobblecheck and see if blades and fletching are in line if not this can be a problem.
