FAQ
Do these nozzles require tuning?Light calibrations can optimize smoke control and drivability, but many mild LB7 builds run 26 LPM tips with stock turbo/fuel and stock-like manners.
Can I install tips without pulling the injectors?No. The injectors must be removed, cleaned, fitted with the new tips, and balanced/verified on proper test equipment.
What else should I replace while I’m in there?At minimum: injector seals, return line components, and any corroded high-pressure lines. Consider a healthy CP3 and fresh fuel filter to protect the system.
How does 26 LPM compare to other sizes?26 LPM is a mild upgrade. Larger options (31–44 LPM) support bigger power but generally need more airflow and tuning.
