It will work, but its in my opinion not the best way of tuning. It tricks the ECU into thinking the fuel pump is not working as efficiently as it could and turns up the fuel pressure. This will give you more HP and also a potentially ticking time bomb with the Fuel pump. Long term issues i am unsure, maybe borewash due to increase fuel flow from the tuning box.


A re-map is programmed thoughout the rev range under different loads makign sure the cars is running its correct amount of fuel for the conditions.
