Get More Power From Your Civic Si — Without Sacrificing Drivability

Your 2017–2025 Honda Civic Si deserves more than a generic off-the-shelf map.

At Kugan Tuning, we build a custom calibration around your exact Civic Si, your modifications, your fuel, and your goals.

Whether you’re running a mostly stock L15B7, full bolt-ons, ethanol, an upgraded stock-frame turbo, or a full big-turbo setup, we’ll dial in your combination to deliver the power and response you’re looking for.

Built for Stock Turbo AND Big Turbo Civic Si Setups

We can tune combinations including:

• Stock turbo

• Intake and exhaust upgrades

• Front-mount intercoolers

• Downpipes

• Upgraded fuel systems

• Flex-fuel and ethanol setups

• E30/E40 blends

• E85-capable builds

• Upgraded stock-location turbos

• Big turbo kits

• Custom turbo setups

• Higher-boost performance builds

• Built-engine combinations

Power Is Only Part of the Goal

Anyone can turn the boost up.

The challenge is creating a calibration that makes strong power while maintaining the drivability and engine protection strategies needed for a performance street car.

Our goal is simple:

Maximum usable performance with longevity in mind.

We don’t want your Civic Si to feel good for one or two pulls. We want a strong, predictable powerband you can enjoy every time you drive the car.

Your Tune Is Built Around YOUR Setup

We don’t simply send the same calibration to every Civic Si.

Your calibration is adjusted based on your specific combination, including:

Boost Control

Boost targets and control are calibrated around your turbo, fuel system, modifications, and performance goals.

Fueling

Fueling is adjusted to provide the commanded air/fuel ratio throughout the operating range.

Ignition Timing

Timing is optimized based on load, RPM, boost, fuel, and your specific setup.

VTEC & Cam Control

Camshaft and VTEC strategies are optimized to help improve response, torque, and the overall powerband.

Throttle & Drivability

Power doesn’t matter if the car drives poorly. We work to maintain smooth throttle response, idle quality, cruising behavior, and predictable power delivery.

Going Big Turbo? This Is Where Custom Tuning Matters.

Once you move beyond the factory turbo, your Civic Si’s airflow and boost characteristics can change dramatically.

A big turbo may require completely different boost control, fueling, ignition timing, cam control, and torque management strategies compared with a stock-turbo car.

That’s why your calibration is built specifically around your turbo and supporting modifications.

Whether you’re building a responsive street car or a higher-horsepower L15B7 setup, we’ll work to create a broad, usable powerband instead of chasing a single peak horsepower number.
