Would be interested to see your IAT values and IAT vs trim logs. My car takes on a lot of heat and holds it, messes up my trims by 2-4% depending on intake temps.

Did some logging with my elm327 a while ago on IAT vs ambient air temp and in traffic mine can get 20 C or more above ambient and hold it for quite some time. Suppose having headers directly below intake is not good
I have actually covered my Intake and air box in heat reflective aluminum tape. This has reduced the difference between ambient and IAT by 50% ie I now rarely see over 9 C difference in traffic in summer and it recovers to 2 to 5 degrees quite quickly. Also removed the plastic piece on underside of bonnet on drivers side (couple of plastic clips) to let heat out at low speeds.
Will send the before/after data logs when I find them.
Thanks again.
