sometimes ppl post baseline dyno of stock focus and its 106whp.. sometimes its 115whp.. and some people get gains from fiddling around with the stock cams.. so i'm thinking the 'gains' ppl are getting might just come from the cams being set properly to TDC when the timing belt is put back on.

and when they do the dyno for some of these products we don't know if there is an enormous fan pointed straight at the cone filter blowing cold air on the 'after' run

i'm thinking for modifications like those its more for the fun of playing with you car rather than actually getting more performance..
