I have a banks idash in my truck and one of my parameters is density altitude.
The lake we frequent in Nebraska is 2800’ elevation. However even in the cool mornings we see a DA of 5500-6000’. During the mid day heat closer to 7-7500’. This is what the engine thinks the altitude is and performs accordingly.
My old 20 sl450 was gutless here when loaded up with people and 1k of lead.
