Yes we recommend a tune because of a large gain in power. But some people run it without a tune, it does run much leans and sometimes can give error code but it runs without a tune. If you want a very nice tune to go with the muffler that is a solid performance gain and better fuel economy try our TD ecotrail turbodynamics.mybigcommerce.com/td-ecotrail-250hp-ecu-reflash-for-2017-2022-sidewinder-srx-and-ac-thundercat-zr9000/
