Even with the high volocity throttle body it will need a custom tune because the port size of the throttle body is different and the MAF is right in the center of it. Which means different amounts of airflow at any given time around the MAF and the stock calibration will be off.
What's your opinion on porting the inlet of the s/c? Is it even worth it? Also, IF I got the inlet ported but didn't get a bigger TB, would that cause any problems?

The only reason I was planning on getting a new TB is because of the s/c inlet porting (and IC in the future).
