like i said i'd like to see proof, say if you lose 8hp up top only to gain 1ftlb of torque in the low end, that doesnt sound too good to me. but it improved the low end didnt it. or say if there's hardly a difference at all, i'd want which ever one is cheaper.
i know i didnt notice much of anything when i put the dc sports 4-2-1 on my car.
