FAQ
How much power will an 85% CP3 support?Actual support depends on injectors, tuning, turbo airflow, and fuel quality. As a rule of thumb, an 85% over CP3 can support substantially more fuel delivery than stock and is commonly used in high-horsepower LB7 builds. Pair with appropriate injectors and tuning.
Is tuning required after installing this pump?Yes. While it will bolt on, tuning is typically required to properly command and utilize the additional flow capacity.
Does this pump include a new FCA (fuel control actuator)?Yes — reman units from Industrial Injection include a new Bosch fuel metering valve (FCA).
What about the core charge?A refundable core charge applies. Return an acceptable LB7 CP3 core to receive your refund.
