That's a milestone in its own right: the first 911 Turbo generation where the S received meaningfully different engine hardware, not just a software bump, over the standard car, proof of how much engineering ambition Porsche poured into this platform.\u003c\/p\u003e \u003cp\u003eWeistec's ECU tune treats that factory hardware as the strong foundation it is, recalibrating boost, ignition, and fueling to OEM-level standards rather than layering on a generic piggyback solution, and every factory protection system (knock control, thermal management, OEM diagnostics) stays exactly as engineered. Across this platform that translates to roughly 40 hp and 37 lb-ft of genuine, verified gain, real momentum added on top of what was already a thoroughly capable factory calibration.\u003c\/p\u003e","brand":"Weistec Engineering","offers":[{"title":"Default Title","offer_id":47875224699036,"sku":"05-038-00193-9","price":2699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/3206\/5436\/files\/ea839tt_ecu_1_9994b00d-2470-4a58-9bed-dbbd331a16ca.jpg?v=1791760387","url":"https:\/\/daroracing.com\/products\/porsche-911-turbo-turbo-s-991-1-ecu-tune","provider":"Daro Racing","version":"1.0","type":"link"}
