Pretty typical of front mount intercooled Century systems, you are not producing any boost until you are past the throttle position that crosses over Atomopheric pressure and closes your bypass valve/valves.
You are dumping most of the heat before the intercooler via your bypass to atmosphere.
So you have a very large heat sink at ambient temps ready to soak up any heat the blower makes when you initially hit boost.
The longer you stay in the throttle the hotter that intercooler brick gets then pretty far down track the IAT will start to rise, this varies hugely with intercooler size, airflow across the intercooler, Which supercharger you are running, where you are getting your intake air, and how much boost you are running.
It is perfectly normal with your system to see reletively low IAT on a short run with or without Meth.
Many times discussion takes a turn in another unintended direction which can help the whole community learn.
The point I am making is about IAT sensor Placement with use of Meth injection, and the possibility to get false readings.
