Tuning Kit Forge Valve Small Spring

This set is designed to help you adjust your diverter or blow off valve to ensure peak efficiency. If you notice excessive release or diminished boost pressure, a more robust spring may be necessary. The set contains four springs with different tension levels suitable for various turbo pressure zones: Green (5-15 PSI), Yellow (15-23 PSI), Blue (23-30 PSI), and Red (30+ PSI).

The springs are versatile and can be used with numerous types of dump valves. They are also compatible with the FMDVTUN spring kit for adjusting twin-piston atmospheric blow off valves. You have the option to purchase the complete set of springs or select individual springs, with colors signifying their respective strengths.
