Most guys only data log under full throttle and if they actually datalogged during normal driving, they'd see a very different picture, regardless if they had an upgraded charge pipe and/or IC. A metal charge pipe will most definitely retain more heat during normal stop and go traffic.
I wish some vendor would just make a hinged plastic clamp that fits completley around the OEM charge pipe neck at the throttle body. It would support and strengthen the failure points and would be cheaper and easier to install plus it would be far better at dealing with heat soak and sealing for boost leaks.

even completely stock the iat will be 20-30 degrees higher then ambient temp...that the general short comings of air to air system.
Your basing your statements on elementary physics and looking at the whole system. BMW uses a combination of mechanical, electrical and software for the cars propulsion.
until you do the research on how the bmw dme works, air to air systems and the n55, your not going to get it.
This will be my last post about the issue.
