There is a slight delay in the time it takes for air to travel from the MAF to the TB and the closer it is, the quicker the throttle response.
From what I read, the closer the MAF is to the throttle body, the quicker the throttle response and the better the engine's high end performance but it's worse for torque and low end performance. The dyno results show that slightly more Tq is made with the Injen though (most of the intakes create Tq). The extra turbulence in the air near the TB is what causes the idling issues and for the fuel trims to be off so much at idle. But on the high end, the faster air flow makes the air less turbulent and it creates more power.

Why would the MAF sensor placement have an impact on throttle response? Are you suggesting that the throttle acts differently based on where the air measurements are taken? I assumed it was just based on throttle mapping and the actual air passing through the throttle butterfly....
