Could somebody help how to get this turbo gauge work with right numbers All info I have of it is this: BoostPressureRange=(-50, 2, 0, 315) // kPa (for turbo-chargers only) what i would like to do, is to have 0 Bar boost at 6 of clock. And 5.5 bar boost at 5 of clock I have messed with the number for many days and i just don't understand what those values mean.
