I have a amazing idea for you.
I have a supercharger, and i can get your engine supercharged, if you're in Islamabad or rawalpindi.
The boost is safe. It has a max boost of 6psi.which is enough for this engine. And later on you can add emanage blue and tune it to achieve smoother curves and more power gains.
