You are correct that some of us Edelbrock owners did complain initially about the high IATs, me being one of them. However, we have learned that Edelbrock purposely placed the TMAP sensor almost in the intake port to assure worst case conditions will be monitored. Edelbrock has developed their tune accordingly to this condition. Once the system has been bleed properly, none of us have experienced a loss of power due to high IATs, even in 90*+ days. Like my tuner said, 150* IAT isn't bad after several pulls. He's seen much worse in the CTS-V.
