It depends on your tuner I'm sorry to say as there's no perfect answer. I was going to tackle this question with all turbos at one time, but somewhat gave up. Reason being with Tuner A you can get a VF22 at full boost at 3500 RPM and with Tuner B it will be 2800 RPM. It can be due to a customer's wishes and/or the tuner's skill so there is really no fixed RPM and you also have to consider supporting mods that add to the googplex of variables.
