IAT's are the intake air temperature after the supercharger. I have a data logger (my track doesn't like them so I put it in the glove box out of sight) With the data logger I record engine coolant temperature, intake air temperature, throttle position, vehicle speed, timing advance, supercharger boost and rpm. I want to go back to an old log to see if I have more timing advance with the new heat exchanger.

Thanks for the hot pressures Jane. If I can get the rear of the car to stick as well as the front currently is, the car will qualify as "stupid fast". I'll take video the next time. Hopefully with Stoptechs.

Jane, you've always helped. Now if I'd just learn to listen!
