Im telling PPK Stage 2 because it uses the same hardware as 1M (extra cooling) but PPK Stage 1 its the same in performance figures, just that when the car has been running for a long time or you have driven it hard it gets hotter than a car with PPK 2 so short story PPK 2 maintains a more stable performance even if running the car in a hard way
