FL5 Civic Type R Custom Calibration

Unlock the full potential of your FL% Type R with a precision custom calibration from Leto RaceWerks. This is not an off-the-shelf file. Every calibration is developed specifically for your vehicle, fuel quality, and hardware configuration to deliver maximum performance with factory-level reliability.

From stock vehicles to big turbo and fully built engines, our tuning process focuses on safe power, smooth drivability, and consistent performance in real-world conditions.

We support a wide range of configurations, including:

• Intake and intercooler upgrades

• Downpipe and exhaust systems

• Ethanol blends and flex fuel setups

• Fuel system upgrades (LPFP, HPFP, injectors)

• Hybrid and big turbo systems

• Built engines and high boost applications

• Port injection integration

If your setup is unique, we build the calibration around your specific configuration.

Mechanical health must be verified prior to tuning. Power gains vary depending on hardware, fuel quality, and environmental conditions. For off-road or motorsport use where applicable.
