The N75 can work, how much boost you are able to achieve with it and your setup depends greatly on your hardware configuration. The wastegate spring will generally determine how much peak boost you can run.

You'll typically want to tune the N75 with either GPO1 or GPO2, and we typically suggest using the basic duty cycle maps to get started (MAP vs RPM is the most common axis setup for this).

Also, your N75 plumbing isn't very clear, but from the looks of it you have the wastegate and boost source lines swapped:
