FAQ
Will this 10mm CP3 work with stock injectors?Yes. It can be used with stock injectors; however, benefits are maximized with proper lift pump and tuning. Ensure commanded rail pressure targets in your tune are appropriate.
Do I need a lift pump with this CP3?
Strongly recommended. A quality lift pump helps maintain consistent supply pressure and protects the CP3 from cavitation. See our 5.9L lift pump options.
Is tuning required after installation?
Not strictly required for basic operation, but performance gains and drivability are improved with appropriate tuning for your setup.
What core units are accepted?
