Hks Fuel Cut Defencer (FCD)

What this Fuel Cut Defencer does is simply adjust the signal that runs to the ECU controlling the fuel cut. So you are able to adjust the unit to make the fuel cut kick in much later and gain more power/ wind up the boost. A lot of our customers install this unit and one of our fuel pressure regulators and end up with a decent power gain. You can check out our range by clicking on the Fuel System link in our store categories to the left!
