i think u got it wrong liao.. abt power pass...
think u read it at the wheel mag frm ADM.
its a device that cuts off ur aircon compressor when u fully
depress ur accelator. cosing more torque.... thus is like more
power.
its a electroncic device.
which can be made if u knoe ur electric homewrk well.
--- if u drive wif ur aircon off, more power...
same same ... to the power pass.
