This EDC17CP14 calibration suite gives the 2009 Audi A6 3.0 TDI V6 a stronger mid-range punch, removes the factory speed limiter and provides modular deletes for DPF, EGR and intake swirl-flaps. Eleven ready-made variants cover everything from a mild Stage 1 to aggressive Stage 2.9 setups, each with optimised torque structure, boost control, rail-pressure and injection timing while knock, lambda and DPF temperature protections remain intact. Flash the full binary via OBD, bench or boot with Trasdata, FLEX, KT200 or any EDC17-capable tool. Original stock file is included for quick rollback. Motorsport/off-road use only.
