Which file to flash? What are my tuning options?

JARblue

The one with SZ tune in the file name is the one you are paying Seb to custom build for your car. Funny that Stock Z can also be abbreviated the same way though - your confusion makes sense at least.

Your choices are virtually unlimited. Seb can build any map you want, so you can have a variety of maps customized to your liking. You just have to tell him what you want.

Once you have a base tune with the mods installed, then you can do some logging for Seb. That way he is customizing the tune for your Z instead of giving you a generic tune that doesn't necessarily take advantage of the go-fast parts you have installed.
