Cost! If I can tune the carb for proper AFR I won't bother with EFI! But because of my elevation and the fact I travel a lot, I'd hate to have to retune every time I drive down the hill. We shall see!
I too live high elevation. It would frustrate me a lot if I we’re to change jets every time I do dropped or climbed a couple thousand feet. I wouldn’t leave town with it.
