^ Why wouldn’t valves affect power? Do they not restrict airflow?
For M Engineering’s Stage 3 tunes and up, an exhaust is “highly recommended” on their website.
Also it doesn’t matter if Soul doesn’t post power numbers. They don’t want to be held to dyno proven gains, I get that.

Does your dealer bother you for having a Tune? I'm coming from an M4CS to a 911 Carrera and my car is slow af. I have akra exhaust that need to be installed.
