I fail to see how the boost would vary with temperature, considering that the ECU can run the charge up as high as it can until it begins to detonate. That would be the "hard limit" on boost. When you have that musch intake pressure going on, it isn't going to make a diddly bit of difference how free flowing the intake is UNTIL you reach massive flow rates, at which point you could lose pressure due to the restriction. I don't have any specs or scientific evidence, but considering how small the engine displacemnet is, and how low rps these things spin, I still say any cold air intake, or other fiddling with the intake to "improve flow" would not net any tangible difference.
