Frequently Asked Questions
Q: How do I pick the right PRV set point?
A: 2000 BAR suits stock to mildly modified trucks. Higher BAR (e.g., 2200–2600) is for aggressive builds; see Exergy’s other PRVs in our fuel rail/CP3 section.
Q: Will this fix a weak stock PRV that vents early?
A: Yes—replacing a tired or low-set PRV can restore stable rail pressure under load.
Q: Do I need custom tuning?
A: Not for stock fueling. For larger injectors or stroker CP3s, confirm your calibration maintains commanded rail within sensor limits.
Q: Any core charge?
A: No core charge on this PRV.
Q: Warranty?
A: Covered by Exergy’s manufacturer warranty. Keep proof of purchase and follow proper installation practices.
