It's the wastegates that came with the supplied turbos, so I'm assuming this is internal? Sam even suggested adjusting the wastegate spring, but the biggest drawback is accessibility.
The local shop is going to install GTM Stage II on a 370Z soon. I'm told they've done installs for 350Zs, so I'll get with them in a few months or even in the Spring to see if they're comfortable working with the wastegates.
The last resort is MBC. I just wonder if anyone used one with our cars and are running 91 octane map.
