had my 2010 muscle dynoed at copperhead dyno service this weekend. mods are V&H slip-ons, amsoil filter, pcv and topless. the base line was 111.4 hp and 81.75 tq and after the tune put down 118.5 hp and 85.78 tq. i am happy with the numbers and it runs way better all around. not sure how these numbers compare to bikes with simular mods.
