Question type: Car Customization

I want to install a tomei exhaust and a cobb sf filter

ecu tune? or i should get a pro tune on it?

I doubt you need a tune for just an exhaust and intake upgrade. Changing the boost is another thing.

I did something similar it won’t affect anything as long as all the sensors on the exhaust are in the same place.
