Got the newer model one on my car. Car performs as it did with the standard bov. No problems with boost. It might be how you put the bov on the adapter. There is a rubber ring that is meant to be there, but if you didn't have that u wouldn't even make 10 pounds of boost because it would all leak.
and to "The Mafia," what do you do mate, just go around searching for every bov topic and pasting the same comment every time? no one cares about your standard bov holding 100psi boost. He wants help with this and if you cant help then just shut the hell up, simple
