Throttle Body: The throttle body and plate is what let's air enter the intake to mix with fuel. The more air you can get in there the more fuel the computer will dump into each cylinder. Overboring your throttlebody is a good way to get 8-10HP. You must take your throttle body manifold off and send it to RC Engineering. RC can modify the stock throttle body for $249. This price includes the throttle body boring, oversized throttle plate, lightly sanding the shaft, and countersinking the throttle plate screws.
