The boost spikes to 22ish but hold a steady 20psi throughout the powerband. The car has direct injection & runs almost 2200psi fuel pressure.
I will let the videos do the talking if there's any questions, feel free. I was completely impressed with the car, feels as powerful as my stg2 skittle was.
Enjoy!!!
