So when you lose chuff sounds,
- the engine speed does not hiccup, jerk, whatever? It continues running smoothly at the commanded speed?
- if smoke is turned on, if you run slowly (where you get distinct puffs) do the puffs occur when you'd expect the chuffs...like 4 puffs per driver-wheel revolution?
