D1SC head unit, ProCharger degas tank and ProCharger piping from my Stage II kit for $1,900.00 shipped anywhere in continental US. Piping is fabricated with flange for big red race valve rather than the standard surge valve. Kit was purchased new from Evolution Performance in spring of 2011. I am upgrading to F1 and I have already fabricated my own aluminum piping and custom degas tank. Head unit is in working order and currently on the car.
