This tune unlocks significant power potential, with Stage 1 and 2 tunes offering up to 542 HP and 581 ft-lbs of torque on E85 fuel. For even greater performance, Stage 1 \u0026amp; 2 Plus tunes, requiring an upgraded High-Pressure Fuel Pump (HPFP), can achieve up to 604 HP and 660 ft-lbs of torque.\n\nThe IESOVZ21 tune supports various fuel types, including 91, 93 AKI (95, 98 RON), and E85\/TrueFlex ethanol blends. It features advanced capabilities such as anti-lag launch control, rolling launch control with brake boost enabled, instant launch-RPM setting via the cruise control stalk, and the ability to default auto-start\/stop to off. The tune also offers an enhanced exhaust overrun and crackle feature in Dynamic drive mode. For users seeking maximum output, Stage 3 tunes, designed to pair with PURE800 twin turbo upgrades, can reach up to 741 HP and 688 ft-lbs of torque.\n\nInstallation and use require the V4 IE POWERlink flash tool. The tune is registered to the vehicle's ECU and is non-transferable, except in the event of vehicle ownership transfer. Note that 2021+ models have advanced security locks preventing Stage 2 Transmission Control Unit (TCU) tuning; Stage 1 TCU tuning is compatible and included with all Stage 1 and 2 ECU tunes. Hardware upgrades such as an intake, turbo inlet pipe, and intercooler are optional but recommended for maximum power gains.","brand":"Integrated Engineering (IE)","offers":[{"title":"Default Title","offer_id":52688891773240,"sku":"IESOVZ21","price":899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687906428.webp?v=1784898345","url":"https:\/\/store.motormia.co\/products\/integrated-engineering-ie-ecu-tune-for-audi-b9-b9-5-2-9t","provider":"MOTORMIA","version":"1.0","type":"link"}
