why does it always come down to how much HP something makes? ported TB's show some gains...but the most important improvement is throttle response. why some people get so caught up in chasing numbers they forget there are other variables in the mix is beyond me.
i haven't done before and after testing with mine, but i suppose next time i hop on the dyno i will. and i'll do it in conjunction with a ported TB just for S&G's.
looking forward to your results OP.
