FAQ
Will this CP3 support mild tuning on my LBZ/LMM?Yes. A healthy reman CP3 is suitable for stock and mild calibration changes. For larger injectors or high-hp goals, consider upgraded CP3 options.
Do I need to replace the FCA/regulator when swapping the pump?
We strongly recommend inspecting or replacing the FCA to ensure precise rail pressure control. See our FCA search link above for LBZ/LMM parts.
Is custom tuning required after installing this pump?
No for stock trucks. If your truck is tuned, verify commanded rail pressure and logs after install.
How is the core charge handled?
Return your rebuildable like-for-like CP3 in the provided packaging. After inspection, your core deposit is refunded according to CPP Diesel’s policy.
What symptoms indicate my CP3 is failing?
Low rail pressure under load, hard starts, surging, and fuel-contamination codes are common indicators. Always verify with proper diagnostics.
