I'm going to guess it's the manifold more the than TB based on what shows the most improvement across similar four cylinder turbos (Miatas and things like Evos/DSMs). The air temps were fairly well addressed with two large fans. It might have been about a 2c hike over what I'd normally see on the street. And we let it cool down between runs. Far easier than doing this stuff on the street. I might draw up a power graph in DLL and it compare it to the dyno curves since I don't have a gtech available.
