Is not like there's a mass of warm air from the DP limiting the effectiveness of the intercooler... the IC gets fresh air.
I'm still not sold that keeping the heat in the DP does anything for performance of the DP. Keeping the heat out of the intercooler, sure! But I don't know that there's any real benefit to exhaust flow.

I'm okay with that. I'll let you know if I ever come across any relevant "hard evidence", but I do recall at least two instances where I have heard people in hot climates complain about their car running shitty and after it's suggested that they heat wrap the DP, and reset the ECU, the problem goes away.
