One of last week’s jobs; After a CSR clutch upgrade and the addition of the Courtenay Pro Alloy charge cooler kit, a mapping session was carried out to boost the power and torque on this VX220 Turbo. The car was already fitted with a 63.5mm exhaust system and had a VXR turbo unit with OE actuator. Power was increased to a manageable and useable 280bhp.
