I know the SVT's will run fine on 3L's with the stock 19lb injectors. The non SVT's which have smaller 17lb injectors will need a set of 19lb injectors and I've heard the car will still run on the stock ECU because the change in fuel is within the ECU's adaptability. A tune in either case is always optimal.
