Tbh you don't have alot of choice if your not running pocketed pistons. Mine was still making power at 6.8k on a T4 with this cam. I have built a new engine with pocketed pistons and have decided to keep my AB07 cam, having been out in T4 cars running BD16's, i feel the AB07 makes for a nicer drive on a road with the way the power comes in.
