Had a customer today ask about changes when moving to 6K feet. Being at sea level in Virginia, I couldn't answer that question. Anyone here know what has to change other than the usual answer of "tune".

 

On an injected motor the pcm will take care of the tune, the higher altitude will register on the MAP sensor and fuel and spark are referenced off of that.

He will be disappointed with the power up there, I think he will lose about 18% ouch.

 

Yea, if I recall correctly, stock LT1 F-Bodies will run about 15.0-15.5 in the 1/4 up here (about 5800 ft). That's what I've heard, at least.
