Frequently Asked Questions

Do I need a tune after installing +30 nozzles?
Yes — ECU calibration is required to safely manage fueling, rail pressure, and EGTs.
Are these genuine Japanese MCR nozzles?
Yes — manufactured in Japan to MCR specification for consistent flow and reliability.
Will they increase smoke?
With correct tuning and healthy injectors, smoke is well-controlled and often reduced compared to untuned or mismatched setups.
What supporting mods are recommended?
Turbo upgrades, intercooling, exhaust upgrades, and accurate monitoring are strongly recommended to take full advantage of the increased fuel delivery.
