The air density advantage stabilized the temp side. but tuning changes are still necessary with elevation changes. My understanding is, that is in part from the ecu varying the tune. but the turbo situation doesn't really want the change. Which is evident in the bd box numbers needing to be richer as I go up in elevation. not leaner like a NA motor. Can a person stabilize the barometric side of the sensor?
Will this make for more or less tuning?
