Alltitude tunes
I can't speak for other tuners, but it's something WE like to know, as this is certainly taken into consideration!
i have that same questions because my truck runs okay where I live which is high altitude but when I go back to sea level places like TX and CA the truck runs great. So now that I live here I'm going to do the home pulls (dyno pulls because we don't have a dyno any where close for about 200 miles) and then I'm going to send off my info to see if Troyer can redo my tunes to fit the truck and location.
