The latest Gen 4 might have a fresh face, but underneath it's still a GD-6... and after thousands of these platforms, we know exactly what they want.
Solid. Reliable. Repeatable.
Because the best tune isn't the one that makes the biggest Facebook claim... it's the one that's still performing perfectly 100,000 km later.
