Frequently Asked Questions
Q: Are these injectors NEW or reman?
A: NEW Exergy units, flow-matched and balanced.
Q: What CP3 should I run?

Q: Do I need custom tuning?
A: Yes. Proper tuning is required to manage rail pressure, pulse width, and smoke control.
Q: Will these fit early 2003–2004 trucks?
A: No. This set fits late 2004.5–2007 common-rail 5.9L only.
