On one of the GMC sites is mentioned plumbing in a propane system that kicks in whenyou put the pedal to the metal.seems like an easy way to boost for those hills. any thoughts on this?
In urban areas I noticed a lot of propane busses in the junkyards. These were simply modified gas motors and I think they had a secondary injection port to add the extra gas during an acceleration..kind of like a four barrell carb kicking in with extra fuel flow. I guess it as a GM cheap modification.
