Car is stationary this is the worst case scenario to punish the system as much as possible.
Shortly after filming we did see it hit 12.3c (54.1F) however we were getting ready to race so stopped filming....it may have gotten even lower but we ran out of time. Either way it shows we are hitting better than the GM spec with a HVAC multi meter so there is no fudging and videos don't lie, IAT2 results are also in the 1st video so keep watching.
