Hi, I put this line in the .INI file of my engine: BoostEffects=(100,0.02,0.006) The boost has 10 steps, at 2% more fuel per step, the engine should use 20% more fuel at boost 10 compared to boost 1. Am I right? testing the car, the difference in fuel use between 1 and 10 is much less, around 5%. Is the FuelConsumption parameter the consumption for boost 1? Any clues?
