because unless you are built, you arent gonna see dick for gains with the skunk2 TB...for the money I would just save up and get ITB if you plan on doing anything worth a damn to the motor if your plans are N/A...if you plan on going turbo...again dont waste your money.....a Huge Skunk2 throttle body if you go turbo should be last on your list to squeez out a few extra ponies.
