Just wondering if these '15's are running crazy lean from the factory?
The tunes I have looked at were pretty similar to the 13-14s. Can you display AFR in the dash? Should hover around 14:1 while you are cruising. I would say the heat difference you're feeling could be because the engine bay was redesigned. Not necessarily running hotter, but you might feel more heat coming off of it.
