Lol so which is it....I know that a SD tune isn't going to adjust for altitude and temperature will it? I'm looking for some good tuners opinion and knowledge...
It doesn't adjust for altitude, but it does adjust for temperature...that's why you have an IAT sensor which is used heavily in SD calculations.
So unless you plan on driving to the top of a mountain and then back down, I would not be scared to run an SD tune given the varying weather conditions.
Been running SD now for about 3 years and have gone through 90* humid summers and 10* bone dry winters with no issues and I always keep an eye on stuff with a dashhawk and wb installed.
