Frequently Asked Questions
Q: Do these injectors require tuning?
A: Yes. 100% over injectors need proper calibration to manage fueling, smoke, and EGT.
Q: Will my stock CP3 be enough?
A: For best results, pair with an upgraded CP3 (e.g., Exergy 10mm) and a quality lift pump to maintain rail pressure.
Q: Should I replace injector lines and seals?
A: Highly recommended on LB7 due to age/corrosion. New lines, return kit, and fresh gaskets help prevent leaks and contamination.
Q: Is there a core charge?
A: Many reman sets carry a refundable core charge. See product options at checkout for details.
Q: Warranty?
A: Covered under Exergy’s manufacturer warranty when installed with proper filtration and supply pressure.
