Most guys that run the 84.5 or 85 claim that the power gains come in the middle of the curve,basically picking up some midrange power and torque. Your final numbers on the dyno may not be affected much but theres another thread in another forum with guys talking about this subject. All claim to get better throttle response. If im correct I wanna say anything over the 85 mm will require a tune and you will not see any positive results on a naturally aspirated engine. Heres the link to that thread :
