⚙️ Product Overview

The main piston spring plays a key role in how your DV+ performs:

• Controls piston preload and response
• Works with ECU-triggered operation
• Helps maintain consistent boost pressure

Over time, springs can:

• Lose tension
• Affect response
• Cause inconsistent valve behaviour

Replacing with the GFB 6117 restores proper function without needing a full valve replacement.
