2013 800r XT Max. I have a buddy with the same rig. He’s put a muzzy slip on exhaust and believes he can outrun mine now. Would a CV tech primary alone out do his exhaust gains? Is there any secondary adjustment that I can do to compliment that primary without going full replacement?We have similar wheel tire setup. We bought them a week from eachother and mine has been faster on every drag race. Thanks in advance and please give all recommendations you think of
