    Need to know which Engine Management. The car needs to be retuned. It is overboosting. PO546 is the EGT sensor. I am assuming who ever modded the car removed the EGT sensor. All of these are common problems. Google search the code number + Subaru to get more detailed info.

    Use the LWG map from Cobb to help with the overboost problem. The EGT sensor is only there to make sure the uppipe cat is alright; since it's removed (most likely), it isn't needed, so just do the resistor fix.

    You'll probably have to obtain it from the Cobb site. Unless the car has been custom tuned, that'd be my recommendation. If it has been custom tuned, you'll need to go to a shop and get the boost tables adjusted.
