FAQ
Do I need tuning with these nozzles?Yes. Proper ECM calibration is strongly recommended to control pulse width/timing, rail pressure, smoke, and EGTs.
Will stock CP3 and turbo work?R1 (100HP/25%) can run on a healthy stock CP3 and turbo with correct tuning. For heavy towing or harder use, consider upgraded air supply and monitor EGTs.
Are these genuine Bosch cores?Industrial Injection starts with genuine OEM Bosch nozzles and extrude-hones/balances them for the target flow.
Are they sold as a set or individually?These are sold individually. Order 6 pieces to complete a full set of cylinders.
