Overkill... Is the way to go. I used his tune before tuning my own and was good. Just be patient with him as this is not his main line of income. As an aside, there are people up in MA on this board, you should maybe reach out and see if someone would in car tune for you, it would be even better than Overkill's ; ) and for what it's worth, the ported SC is not as good without a ported TB. The TB will provide better airflow to the ported, smoothed SC and better throttle response. Just my $.02
