I'd have figured the allante intake makes more peak power because of the long runners. But maybe I'm used to northstars where a bigger TB is worth like 3hp and costs hundreds... Like I said, the throttle body is going to be just about as restrictive naturally aspirated as it would be turbocharged (percentage wise.) If a bigger TB would get you 2hp n/a, it would get you about 4hp on a boosted motor making 400hp (from boost alone.) Think of it this way, right now your engine is under 14.7 or so psi boost, so air is still getting forced in through the intake system, boosting a car isn't much different from running it at a higher atmospheric pressure like below sea level.
