I just flashed my M-9603-M4C onto my 2018 PP, 6sp manual last night. It feels stronger after the 50 miles I put on it so far. I just chatted with FRPP asking if there is indeed a learning period even though the car has always been run on 93 octane for its entire 16,000 miles to date. They said absolutely yes, it can take anywhere from 50 to 500 miles for the tune to reach its full potential. All the factory safeguards regarding octane adjust and learning are kept in place.
