couldn't you just drive the car to sea level, tune it, drive it back?
No. The boost control isn't gonna be the same at sea level as at altitude.....and those injectors will be at 130% at sea level
Every 2000 feet u go up in altitude the target boost drops by 1-1.25 psi....so he has to be targeting ~30 psi to run 26....
