Unless you get one that is much too small, you will not have any issues with it spooling at part throttle rpms. It is a shear matter of the exhaust flow with the throttle body being mostly closed.

As a for instance, on the wrx stock turbo, it is very small from the factory and it will spool a little bit if you get into the throttle in 5th gear while cruising over 70 mph or so or if you go up a big hill. Put on a big turbo and that goes away pretty quickly.

The main determining factor will still be your right foot
