*Required - Upgrade Panel Filter And Intercooler


With our Haz Stage1+ 35D ECU upgrade calibration we require a high flow air filter and upgrade intercooler to be installed. This allows us to go that little bit further and extract a little more horsepower and torque from our calibration with the lower intake air temperature coming into play

Fueling / Performance Upgrades / Power Figures

Our ECU software is based on premium grade fuel for optimum performance gains as well as engine longevity. Zero modifications are required to go Stage1 however with our Stage1+ calibration you may be required to upgrade your hardware. Contact us if you are unsure on what performance upgrade you require.
