This is true, unless you have a system that can compensate using atmospheric (not the map sensor, another one) pressure sensor and intake air temperature sensor. K-pro and the AEM systems can do this. Once you have that set up, you can change climates all you want and you'll still be good on the tune. If you do not have a system that can change based on those sensors, then you do need to retune (or at least check it) if you have an extreme climate change.
