- side notes to the sand throwing contest so far - I read that the FLT guys contacted Chrysler about the 6.4's performance - apparently the engine is programmed to settle back into a climbing rpm to pull a long grade if the driver holds it in racer mode rather than truck driver mode - pedal to the rug - revving to the governor try an upshift - no can't pull that gear - downshift- rev to the governor and repeat... its not really designed as a hill racer it behaves more like a truck engine...
- not sure what is more complicated about a Cummins common rail injection system vs a modern gasohol engine's system? The Cummins fuel system runs 100's of 1000's of miles before repair in real trucks
- diesel aftertreatment system is more complicated than gasohol vehicle.
spark ignition engines use lotsa fuel when you work them hard. 2x what a diesel wants sometimes.
