I am using my modded version of Bill's 80hp as my daily driver here at 6000 ft + I changed the setings for the factory high altitude compensation maps(low boost fuel, SOI etc) that kick in at 4500 ft.. Bill leaves them at the factory settings I think. made other changes too... Honestly I don't think really notice a lot of difference but I drive pretty conservatively.... It's plenty of power for my needs...
there are also some tranny stuff for elevation as well as rpm shifts at altitude... I am finding more that I need to tweak for the cold starts and winter temps than for the altitude.. .
Hopefully will get more insight when Bill is out for Truck fest this summer in CO
