I live in Southwestern PA (Westmoreland County) and would like to get the 2 degree timing advance on my '17 Frontier. I asked a service manager to ask a service tech at a local Nissan dealership about doing it but they kind of blew me off. There are other Nisan dealerships around but it's difficult to speak to a service tech directly. Can anyone help me out that may know a service tech at a dealership, any automotive garage, or individual who can do this for me in the area? Thanks in advance.
