I Jdm swapped my 03 wrx with an ej205 that has avcs, i got the wiring harness to run avcs and the correct jdm ecu, all but the harness was from Jspec in VA. I am having issues with how the car runs when boost builds up. it sputters quite a bit. I have been told that i need to get it calibrated, just brought to shop to get it to run properly. in the time being, since im at school would i be better off running the Usdm ecu?
