it is a fact that high underhood temps on a vehicle with an IAT sensor will suffer a loss of power and preformance in high heat. last week I had 165 degrees under hood temp (measured next to the air box ) all my vehicles run stronger in the winter here in Phoenix. If I drive up to Flagstaff in August you can feel the differance in power and preformance . and it is not just the altitude all my baro's are working fine.
