It's a messy process. You would have to visit your local dealer and they check your engine serial number to see if can be uprated based on the parts it was built with. Then, they have to make a case file for the uprate. International will make a new calibration for your engine along with a new emissions label that has to be physically installed on the engine before they will allow any programming to be done. You will have to pay for programming and the new label along with any emissions charges applicable since the engine will have more power. This process usually takes several weeks but with covid it could be significantly longer.
