Do the Berk HFC fail emissions? Also, does anyone have a good recommendation for a tuner in the Northern Va area? Right now, I have the K&N drop-ins and the Ark Prototype II exhaust. I plan on adding the Berk HFC so, would that require a tune or is an ECU reset enough for the car to adjust to the curve?
