so i took my bike down and had it tuned after i put in 13.8:1 high comp piston stage two camps, K&N high vel. intake, full sparks and pcIII. it turned like 47.8 horse. few weeks later i put a friends head on with a mild port job and ran same map but seemed like a pretty good power gain. a couple weeks after that i ordered up a +3 throttle body and figured its time to have it custom tuned and a dyno run, here comes the disappointment, it pulled 49's. a fifty once. so thats saying i gained a horse or two out of a head and throttly body? seems pretty lame? could the throttle body being doing more hurt than help?
