I’m a brand new owner to a 2017 WRX and was wondering if I required a tune on the car after installing a cold air intake. I’m not looking directly for power or torque increases, rather just for louder or more defined turbo noises. If the tune is required, do I also need a COBB access port or something along those lines for someone to tune? Any help would be very appreciated. I’m very new to the car community and scene but I hope to be more involved soon.
