— Notes from the tuner
What we did.
The MY13 automatic STi underwent a service and dyno tune session. During this process, we successfully rectified the boost instability and optimized the torque model. This resulted in a remarkable increase of 44 newton-meters of torque consistently across the entire rpm range.
