So I've been running my stratified stage 1 tune for almost a month now. Performance Mods pertaining to this discussion are a Deporacing 5.5" intercooler. My CAT were always, at max, 4° below the outside temperature. Usually closer to 8° below outside temperature. My IAT however would always be at least +15° of what the outside temperature was. Thought that was weird but hey, car pulls really well and my logs looked good. Recently switched over to the Cobb stage 2 tune and my CAT are +12° of what the outside temperature is and the IAT are about +5° of the outside temperature. Just curious why this is? I wouldn't think changing the tune would cause this unless one of the tuners has set a parameter in these two values to trick the computer into thinking these values should be a set % of the outside air? Thoughts, comments, suggestions all welcomed.
