+1 on that. Turbo'd cars normally don't benefit much from an intake like an all motor car would. In some cases, you would actually lose power with an aftermarket intake (without tune) as it messes up how much air flow is coming in and how much air flow the computer "think" is coming in.

Bigger diameter exhuast is the first step for a turbo'd car to get more ponies
