nope... the fuel cut pressure is measuring from the Turbo Pressure sensor that is mounted on the firewall (in a GT4 anyway)... it cuts at 12psi.

Do a search for the Zener diode mod if you want to remove the fuel cut cheaply... cost is around 40 cents. You want a 4.3V one.

Be *very* careful. Watch the boost gauge like a hawk and listen carefully for any pinging.

There isn't much point doing this anyway, as the ECU doesn't have fuel maps for more than 12psi and will just run fully rich and prevent you from making more power anyway. If you install a piggyback fuel computer (S-AFC etc) then you can lean it out to compensate. Do this on a dyno only.
