beats, me dude how you are gonna tune them, but i've heard that it takes hours on the dyno to get the best out of them. Don't use somebody else's settings. as for the pulley i have no first hand experience with them but i've heard they are good but do not offer noticeable gains. also saty away from Unortodox racing ones. they tend to unbalance the engine which will cause damage in the long run
