Remember that paper testing is as much a test of your shooting form (especially how bad you' re torquing the bow) as it is a check on bow tune. If you' re sure your form isn' t the problem, then check for cam lean, limb twist, bent riser (rare problems for a new bow, especially a quality product like BowTech, but not unheard of) and I definitely agree you need to double check your arrow spine.
