Please note that with upgrade turbocharger installed you will need engine tuning. 

Stage 3-5 turbochargers should be used only for professional use. Upgraded intake system as well as performance downpipe and custom software is required in order to achieve the best results.

When installing a new turbocharger we recommend to read our Installation guide.
