So how about an option for increasing intake duration for N/A. I did not see anything on that.
Custom Cams... 
You can't just change the profile of said camshaft.
For instance variable valve timing only alters the cam timing points (i.e. VVT) or switches to a different/alternate lobe profile. (i.e. VTEC)
VTEC is about as close to having 2 different camshafts as there is because in fact there are 2 completely separate profiles on the cam.
Or buy a BMW. They have completely variable lift now on some of their engine lineups in addition to variable valve timing called VANOS.
It takes them just 180 ms to adjust the valve height + - 11mm IIRC what I read before.
Still, it still doesn't change cam lobe profiles.
