The HKS Power Editor is a plug-and-play boost controller that safely raises turbo boost on the otherwise stock GR Corolla for an easy, reversible power bump. It wires inline between the factory pressure sensor and its harness, ships preloaded with HKS boost-up data, and includes a status LED plus a bypass connector so you can switch back to stock any time. On HKS's dyno the gains build from around 2,700rpm, adding roughly 17PS and 3.9kg-m at the peaks over stock. The preset data can be fine-tuned with HKS's free Easy Writer software.
