Go softer so your car can squat down on the launch, and let your tyre pressure down quite a bit for better traction.
I would go the Z32 AFM as there is the option to select that airflow meter built into the Power FC, which will make the tuning process a little easier. When making that sort of power I think you are better of sticking with a product you know works.
Good luck at the drags, I'd say a low 12 is on the cards.
