When I drive my car and put the clutch in for a couple of seconds or put it in neutral my car will sometimes stall mid driving or get close to stalling.

Anyone have any idea why?

Here is a video of my revving:

 

Do you have an aftermarket blow off valve/diverter valve/bypass valve?

Do you have an aftermarket clutch?

 

Yes I a Blitz BoV and stage 3 act clutch

 

It's your bov that is causing it. VTA on maf is no good.
