Cobb recommends that you put the restrictor in any way

you don't need it to .. the cell won't flash but the ecu still references the egt sensor for some closed loop fueling parameters

for $.99 for 5 resistors and 5 minutes of your time just fix the cel cause you may sell the AP and need to do the fix it anyways.
