The Grunter

Grunter Sticker - small

The Grunter™ series is designed as an upgrade that offers quick boost response early in the rpm range (great low rpm torque) whilst delivering a substantial power increase in the higher rpms compared with OEM, typically in the range 30-60%*. In essence, the Grunter™ can be considered the Stage 1 upgrade. For those wishing for more power while retaining most of the low rpm performance attributes, there is also a Grunter Extreme™ option available for some engine families.
