Important note* While the hardware in this listing is compatible with your vehicle it is possible that the required tuning is not. To confirm ECU tuning is available for your car, your vehicle's ECU box code must be identified. If you own VAG COM, OBDeleven, Carista, or have access to factory VW/Audi diagnostic tooling, you can follow this guide to identify your ECU box code. You can also visit either New German Performance shop location and our staff will be happy to assist.

Please note that this turbocharger does not include any ECU tuning. Stage 2 is not referring to the software stage required for this turbocharger. You will need ECU software/tuning that is specifically made for this turbocharger.

Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The target power has been calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel power.
