Hello guys, is it important to dynotune after making upgrades on your car? I.e. exhaust, brake, engine upgrades, tire and wheel change etc.... A car noob here.

Short and sweet answer is get a tune if there is a change to airflow and fuel flow. Anything else nah.

For airflow changes you don't need the tune right away though it would help tremendously in terms of performance and CELs (but there are ways around this). If you don't want to keep paying for a retune get all your parts first then tune.

Anything that will change Fuel flow or a mix like injectors and camshaft, get a tune ASAP.

Yeah, brakes and wheels have nothing to do with engine performance. Just get your bolt on then get a tune.
