It's not just rpm, the whole reason it's called brake boosting is because if you want to keep a turbo spooling the engine needs a load on it.
Just revving it standing still puts zero load on the engine, it takes hardly any throttle to hit that rpm with no load, thus very low flow of exhaust plus heavy throttling of the intake still.

So as soon as a load hits the engine the turbo is going to instantly bog right back down
