The Bad Boy

Badboy Sticker - small

The Bad Boy™ series is designed as a sports or race oriented upgrade that offers quick boost response early in the rpm range (great low rpm torque) whilst delivering a more extreme power and torque increase in the higher rpms compared with OEM, typically in the range 60-120%*. For those wishing for more power while retaining most of the low rpm performance attributes, there is also a Bad Boy Extreme™ option available for some engine families.
