Emanage is still only piggyback, it's limited and can't advance cam timing which the RBC really needs to be good.

With full intake, TB, ,exhaust and RBC I think I'm only just matching a stock Euro for torque up until about 5000rpm
So conclusion.RBC=waste of time and money unless your car is highly modified,I,H,E,cams etc.
