SD tuning and 02 sensors
So doing some upgrades to my 08 Z. One of which being headers and a cam swap. My question is with the new upgrades. Seems how it's SD tuned. Do I need to get new 02s before the new tune is installed? Forgive me if this an idiotic question. Just never had a car with SD tuning before.
