This is achieved through a larger diaphragm surface area and revised internal spring calibration, creating greater mechanical leverage against boost pressure and exhaust backpressure while maintaining fast and precise actuator response.\u003c\/p\u003e \u003cp\u003eWith factory base pressure, the result is earlier boost onset, a broader torque curve, and improved boost retention into higher RPM. Higher pressure variants can further enhance performance, though ECU tuning and recalibration is recommended.\u003c\/p\u003e \u003ch3\u003e⚙️  IWG75 TP WRX STI GDB Spec C EJ207\/MY03-07 VF37 7PSI Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eProprietary Silicon Nomex Diaphragm\u003c\/li\u003e \u003cli\u003eOptional Spring Range: 3 PSI – 26 PSI\u003c\/li\u003e \u003cli\u003eHigh-Grade Billet Aluminium Construction\u003c\/li\u003e \u003cli\u003eStainless Steel Rods \u0026amp; Clevis\u003c\/li\u003e \u003cli\u003eTurbosmart Locking Collar System\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003e📌 Fitment\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eSubaru WRX STI GDB (2002–2006)\u003c\/li\u003e \u003cli\u003eSubaru EJ207 VF36 \/ VF37 turbochargers\u003c\/li\u003e \u003cli\u003eDirect bolt-on replacement for factory internal wastegate actuator\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003e📌 Notes\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eDesigned for factory-frame turbo applications\u003c\/li\u003e \u003cli\u003eECU tuning recommended for higher boost settings\u003c\/li\u003e \u003cli\u003eImproves boost response, mid-range torque, and top-end stability\u003c\/li\u003e \u003c\/ul\u003e","brand":"Turbosmart","offers":[{"title":"Default Title","offer_id":56813706903857,"sku":"TS-0605-4073","price":317.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0906\/1787\/2689\/files\/14543.jpg?v=1792039520","url":"https:\/\/latemodelfordparts.com.au\/products\/turbosmart-iwg75-tp-wrx-sti-gdb-spec-c","provider":"Late Model Ford Parts ","version":"1.0","type":"link"}
