True super tunning is what Kurt described.
I have all the respect in the world for our techs in Archery Shops but to truly super tune your bow is more than just setting it to spec, getting correct draw length, correct poundage, setting center shot, setting correct timing and then finishing off with a paper tune.
But this is all a shop can do in a limited amount of time and to be truthful what 90% of bowhunters are fine with and their skill set can utilize.
That is a basic tune after which super tunning begins and it is a time consuming process which requires either you learn how to do it yourself, get a bow press, draw board, or have a tech who lives with you or is family
Its a frustrating process but once you robin hood bare shaft arrows at 20 yards and your BH and FP are hitting the same spot passed 70 yards it is worthwhile. Super tunning will also greatly enhance your form as you will then learn how grip greatly affects arrow flight, where the sweet spot for your bow is and what arrow /vane/ BH/ FOC your bow likes. It is similar to reloading in terms of the process.
