> Yea there is that trick. Did you also know that below the throttle body there is a black plastic shim that sits between the TB and manifold? Its actaully a restricter, you can pull it out and dremel it so it matches the TB diameter.

that i didn’t know i might have to try that tomorrow. so that i can get a little more than a couple more hp cause i could use anything cause theres only 70 hp stock on the d15b2
