what about all those stickers on the side like nos and type r those are good for 200+ horsepower. even if you get the dyno on those numbers there moters set up and tuned for there parts like when slp does there numbers its not a all stock motor they set up the test to make them look good. 20hp is a moddest number with headers id think more than that... but if you think a supercharger only gives you 50 to 60 why the hell would headers and exhuast and a intake give you the same just doesnt make sense.
