I understand that, but one of the members in this thread said the tune did nothing for performance. Only improved fuel economy. That’s good, but I’m not sure if it’s worth it.
How much does this tune cost and how do you control the maps? Meaning, if I valet my Z, how do I turn on the valet mode? I’m new to ECU programming.
