you can unplug it, remove it whatever... the turbo pressure sensor will not alter your fuel cut at all... it will only give inaccurate readings on your dashboard
the afm (karman vortex) measures air flow... when too much gets in... it cuts
afm signal goes to ecu
fcd wires into ecu
fcd clamps signal you don't get fuel cut no more
and you have the possibility of detonating if you wack the boost up something silly
have fun
