I can understand why they didn't include it in the kit from the start, it involves a lot more tweaking than is practical than just a few back and forth remote tunes, but a blow through setup is always the best way to go with a forced induction setup. Although, car manufacturers have usually found draw through sufficient. With the intake pulling air from within the engine bay though blow through is definitely the way to go.

Where I'm on the fence about the placement of a boost signal in the manifold due to fluctuations, an IAT sensor should be fine in the manifold as the sensor's feedback is buffered.It's matter of how they're constructed, there may be fluctuations in velocity and density but the temperature will be more consistent and thermistors only can only see the change so fast.
