2012+ Coolant System/Overheating

Once you do that, if you still have issues, better airflow at slow speeds is what will need to be addressed, aka radiator fans. I have been through this same issue with my 1975 280z turbo. It can be a challenge to get it perfect when you upgrade a NA car to turbo's.
