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.

During normal driving with little throttle in stop and go traffic, you are not stressing the engine limits enough for heat soak to matter. The timing tables and boost aren't being pushed at such low rpm. Idle heat soak has no effect.
