Fixing that IAT2 sensor depth has to be step one to get more accurate readings......but I think there's only so much you can do trying to REALLY push the car and blower in summer heat n humid New Orleans. With no change at all, your temps will be less this fall. Unless it's raining, and you won't run the car anyway.....the summer heat dome is really socked in for the next 8 weeks minimum. Probably 12.
