Help with tuning it, unless someone here has that exact model, would be just general bow tuning help. You'll need to now what the bow's specs are supposed to be first. Axle to Axle measurement, brace height, maximum poundage of the limbs that are on it, what type of cam system, what draw lenth it is on, etc. Do you have this, or can you get it from Pearson? I'm sure we can walk you through tuning if you have most of the info.
