Hey guys! I have been monitoring my intake manifold temp with my cobb ap and have been noticing some strange figures. While driving around the city my temps would average around 70f but cruising on the freeway at 2000 rpm the temps would be around 110-120f and the outside temp is 50f for reference. The car is a 2018 forester XT. Pretty much stock except for a stage 1 etune. Any ideas what might be causing the spike in temperature?
