Please note that engine tuning is required when installing an upgraded turbocharger.
Stage 3–5 turbochargers should be used for professional applications only. For best results, an upgraded intake system, a performance downpipe and custom software are required.
When installing a new turbocharger, we recommend reading our Installation Guide.
