Stock 2015. New owner. I think I just had my first big heat-related power loss. 90 degrees today, car was already fully warmed up. I was driving ~30mph for several minutes then at a stoplight for a minute. Once I turned onto the next street, I gunned it to wind out 3rd and it was meh -- felt like 3/4 throttle at most. But then after that high speed push, I turned around and did another run and the full power was back.
So -- was this heat soak, and the high speed run force air through the IC to cool it off? Or something more nefarious...
And if it was heat soak, is a FMIC the easiest solution in hot climates?
