I have a 2009 GTI CBFA (MT) and I was wondering what it would involve if I were to swap the stock ECU with a stage 1 or 2 ECU. I would find one with the same engine code, year, etc but I was wondering if the instrument cluster is also paired to the ecu as I have heard you can have immo problems. If you have any information on this let me know as I was planning on buying a chipped ecu and keeping the stock one for dealer trips.
