STI 06-07 HPF STAGE 3 | 250kW
The Subaru STI MY06-07 Stage 3 upgrade starts with our trained technician fitting a cold air intake with high flow air filter and stainless steel 3" turbo back exhaust system to increase the engines breathing capabilities, we then tune your vehicles ECU on the dyno in real time utilizing the latest Subaru ECU tuning software to maximize power, torque and fuel efficiency.
We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicles performance and driveability. At the end of this upgrade we will provide you with a dyno graph comparing the before and after power & torque increase the HPF upgrade has made to your vehicle.
Like all HPF upgrade packages the Stage 3 package is modular in that it allows the customer to add to the package minimising the requirement to spend money twice when and if further upgrades are desired.
