since the VVEL control the openning of the valve, adjusting this *magic screw* also move the minimum valve opening.
I say the valve will not fully close if you want that 300 duration *we are talking about thousand of an inch here*
this is probably why Nissan does not want anybody to play with those screw.
I should test it with my spare VVEL head
edit; after thinking about the problem ,, it could be fixed with a different thickness of valve lifter. so yeah that 300duration could be possible as per what JWT discovered.
