The pictures on the website are different from what you posted in your previous post about what really is in the box!....
I see no "tungsten" and also those "booster" ports are not there... (but it is difficult to see in your picture, so I could be wrong)
Grinder posted a picture, with no booster ports, but 2 additional small holes under the main intake port....

According to me "booster" ports are also not IFMAR legal....
