How would they know what the "correct hospital" is before the extent of his injuries are known ?
Reads to me like they took him to the closest for immediate urgent treatment and the moved to the other hospital that was equipped to perform specialised treatment/surgery required.
Yeah cause the piggy backs (not chip sets) add more fuel but the owners do not add the extra's required.
My Douche-MAX runs a stand alone MoteC ECU compound turbo's// big intercooler/Injectors/Exhaust.
Makes very decent power with very little smoke.... I do a have a "roll coal" button though !
Possibly, if it is an old worn out vehicle.
Newer vehicles, Diesel tuners dump more fuel in to make more power, the black smoke is unburnt combustion.
My Douche-Max rolls lots of coal, More Smoke, More Poke.
