The Stage 1 (485 BHP*) GT2260S Turbocharger maximizes efficiency and air flow compared to the OEM turbocharger. High temperature, Mar-M alloy turbine wheel and twin scroll stainless steel turbine housings are rated for up to 1050° C. This turbocharger is fully assembled with a calibrated electronic actuator and ancillary components for direct fitment to your Audi or VW. 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. The customer assumes all risk if this turbocharger purchased and installed without first confirming the required software is available. No returns are accepted for installed turbocharger kits.

Stage 1 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.
