Developed in-house by VF Engineering's calibration team, this precision engine tune sharpens acceleration and drivability across the rev range while keeping the factory smoothness and reliability that make the RS6\/RS7 so usable every day.\u003c\/p\u003e\u003cp\u003eEach calibration is tailored to the Audi RS6\/RS7 (4.0TT)'s engine and integrates seamlessly with the factory ECU, so you keep OEM refinement, cold-start behavior, and safety systems intact. The result is a stronger, more responsive RS6\/RS7 that feels transformed the moment you press the throttle — backed by VF Engineering's decades of forced-induction and calibration expertise.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIn-house developed calibration for measurable power and torque gains\u003c\/li\u003e\n\u003cli\u003eSharper throttle response and stronger acceleration across the rev range\u003c\/li\u003e\n\u003cli\u003eRetains factory smoothness, cold-start behavior, and safety systems\u003c\/li\u003e\n\u003cli\u003eTailored specifically to the Audi RS6\/RS7 (4.0TT)'s engine\u003c\/li\u003e\n\u003cli\u003eBacked by VF Engineering's calibration and forced-induction expertise\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eSpecifications\u003c\/h5\u003e\u003ctable class=\"table table-striped table-primary\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eVFP.AUD.C8R.ST1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Name\u003c\/td\u003e\n\u003ctd\u003eVF Engineering Performance ECU Software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVehicle\u003c\/td\u003e\n\u003ctd\u003e2020+ Audi RS6\/RS7 (4.0TT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEngine\u003c\/td\u003e\n\u003ctd\u003e4.0TT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSoftware Type\u003c\/td\u003e\n\u003ctd\u003ePerformance ECU Software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch5\u003eVehicle Fitment\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003e2020 Audi RS6\/RS7 (4.0TT)\u003c\/li\u003e\n\u003cli\u003e2021 Audi RS6\/RS7 (4.0TT)\u003c\/li\u003e\n\u003cli\u003e2022 Audi RS6\/RS7 (4.0TT)\u003c\/li\u003e\n\u003cli\u003e2023 Audi RS6\/RS7 (4.0TT)\u003c\/li\u003e\n\u003cli\u003e2024 Audi RS6\/RS7 (4.0TT)\u003c\/li\u003e\n\u003cli\u003e2025 Audi RS6\/RS7 (4.0TT)\u003c\/li\u003e\n\u003cli\u003e2026 Audi RS6\/RS7 (4.0TT)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eImportant Note\u003c\/h5\u003e\u003cp\u003eYour tune is supplied with a VF Engineering HEX cable — you read and write the file yourself using a Windows computer.
