I know how you feel,I am at present trying to get more power out off my engine as it seems to drop off at 6700 rpm,my car has uprev,millteks,plenum spcer,hfcs and a pop charger.I have been told to remove the hfcs and totallly decat it.
can anybody else give me advice on this matter,without going to rebuilds,turbos and super charging.
cheers
