Here we have a 2002 Subaru WRX with a JDM Version 8 swap in it running the factory twin scroll turbo. We installed Tomei Equal Length Headers and a Tomei downpipe connected to a cat-back system. The power numbers aren’t jaw dropping but this set-up is quite quick and having such a wide rev range makes it really easy to drive on track.

Was this tune done on a JDM or usdm ECU?
Also why did you only tune it to 7500rpm when the motor can rev to 8k?

This test was done on a JDM engine. and for the second question, you typically tune around your torque curves rather then the highest the rev limiter will go.
