taking the performance figure into account, the soch does provide better fc. i think its down to the cam design, its made to give better low ~ mid torque, so u rnt trying to squeeze the throttle when accelerating to a particular speed. u can get similar fc by adjusting the cams degree imo, as i have done in my 91. a trip to penang dat took 3hours 15minutes (plus stopping for food), costs less then 40hengget fyi
