I'm going to clean it atleast at every oil change. Might just clean it once a month. Was going to clean my MAP Sensor but couldn't find my deep socket

Overhead POS has went up 4-5 mpg. I'll hand calculate it next time I refuel.

IAT-Intake Air Temp.

Has to do with the fuel mix, if it is dirty it wont read right and the result can be bad mileage

it reads the air temp at the plenum of the head. In cold weather it triggers the grid heaters and richens the fuel mix. This sensor is only effective during times of low boost. After the charger lights = > 10psi its all in the box actually pretty crude a well tuned 12 valve with a perfectly adjusted plate could actually run cleaner. I belive the ADR box is a big step as it is tunable throughout the fuel curve

Throttle response has improved. I now notice that on my Pulse the IAT and Coolent Temp match at startup now.
