My car idles a lot differently now, it used to be around 20 vacuum on the boost gauge, now it's around 10 vacuum. Also, it used to idle around 40hz, now it's around 70hz for airflow at idle. I guess it makes sense that these two would rise together, but why the change? Just the cams made the difference?
