With max cooling enabled it runs the pump as a circuit continuously so you don't have any intake fluctuations. I don't use it on my car as my IAT have never been a problem on a stage 2 tune... although summer is coming up and I'll have to keep an eye on it

On B58's, we have a fast warm up because our oil gets heated up by the coolant; one of the main benefits from the N55.
3:05 mark, he takes off the oil/water heat exchanger.
