392 / 6.4 HEMI Charger, Challenger, Durango & Ram Remote Tuning

More Power. Better Response. A Calibration Built for YOUR HEMI.

If you have a 6.4L / 392 HEMI powered Charger, Challenger, Durango, or Ram running the factory ECU/PCM, this remote tuning service is designed to get more out of your setup safely and consistently.

Your vehicle isn't tuned from a generic file.

We build the calibration around:

• Your vehicle

• Your engine

• Your transmission

• Your fuel

• Your modifications

• Your datalogs

• Your performance goals

Whether your HEMI is stock, bolt-on, cammed, or modified, we use real vehicle data to refine the tune and improve how the entire combination performs.

What Will You Notice After the Tune?

A proper engine and transmission calibration can completely change how a 392 feels.

Depending on your setup, tuning can improve:

• Throttle Response

• Low-End Torque

• Mid-Range Power

• High-RPM Power

• Shift Quality

• Shift Timing

• Transmission Response

• Torque Management

• Pedal Response

• Overall Drivability

The goal is not just to make a bigger dyno number.

The goal is to make the vehicle feel stronger, sharper, more responsive, and properly calibrated for the parts actually installed on it.

Custom Remote Tuning — Not a Generic File

This is a true remote tuning service.

We don't simply email you a one-size-fits-all tune and call it finished.

Here's how the process works:

1. We gather your complete vehicle setup

We need information about your engine, transmission, fuel, and modifications.

2. We build your initial calibration

Your starting tune is created around your specific combination.

3. You flash the vehicle

Using your supported tuning interface and software, you load the calibration into the factory ECU/PCM.

4. You record the requested datalog

We give you instructions for the data we need.

5. We review the log

We analyze how the engine is actually responding.

6. We make revisions

Fueling, ignition timing, torque management, throttle, and other applicable parameters are adjusted based on the data.

7. You flash and log again

We continue refining the calibration as necessary.

Your tune is adjusted to YOUR vehicle — not somebody else's 392.

If your vehicle has a more advanced combination, contact us before purchasing so we can confirm the correct tuning service.

Engine Tuning

The engine calibration can include optimization of applicable areas such as:

• Air/Fuel Ratio

• Ignition Timing

• Torque Management

• Throttle Calibration

• Pedal Response

• Rev Limits

• Idle Calibration

• Camshaft-Related Calibration

• Fueling Compensation

• Knock Control Strategy

• Other Applicable ECU Parameters

The exact calibration changes depend on the vehicle, ECU strategy, fuel, and modifications.

Transmission Tuning

One of the biggest improvements you can make to a 392-powered vehicle is proper transmission tuning.

Depending on the transmission and supported application, calibration can improve:

• Shift Timing

• Shift Firmness

• Part-Throttle Shifting

• Wide-Open-Throttle Shifting

• Torque Management During Shifts

• Downshift Response

• Overall Transmission Behavior

Engine and transmission tuning together can make the vehicle feel significantly more responsive than engine tuning alone.

Knock Analysis Matters

Not every knock-retard event means the same thing.

Part of proper tuning is reviewing the data and determining whether the ECU is responding to actual combustion knock or to noise that can be interpreted as knock.

We don't blindly add timing until the number looks good.

We review the datalog, look at the operating conditions, and make calibration changes based on what the vehicle is actually doing.

During the remote tuning process, we'll also help you understand what you're looking at in the logs so you have a better understanding of:

• Knock Retard

• Ignition Timing

• Air/Fuel Ratio

• Engine Load

• Fuel Quality

• Datalog Conditions

The objective is to make power without ignoring the data that protects the engine.

Experience You Can Trust

Kugan Tuning has years of experience calibrating:

• Street Cars

• Performance Trucks

• Drag Cars

• Road Race Cars

• Drift Cars

• Naturally Aspirated Builds

• Forced-Induction Builds

That experience matters when you're trying to make a modified combination work together correctly.

Your tune is approached as a complete calibration, not just a peak-horsepower number.

What We Need From You

After purchasing, we'll need information about your vehicle such as:

• Year

• Make

• Model

• Engine

• Transmission

• Fuel Type

• Intake

• Headers

• Exhaust

• Camshaft

• Injectors

• Fuel System

• Other Engine Modifications

• Current Tuning Hardware

• Current ECU/PCM Status

Providing accurate information helps us build the correct starting calibration.

What You Need for Remote Tuning

You will need:

• Supported Tuning Interface

• Compatible Tuning Software

• Windows Laptop

• Reliable Internet Connection

• Mechanically Sound Vehicle

Some model years may require an unlocked or modified PCM/ECU before tuning can begin.

If you're unsure whether your PCM is ready to tune, contact us before purchasing.

What Your Remote Tune Includes

Your purchase can include, where applicable:

• Custom Engine Calibration

• Calibration Based on Your Modifications

• Initial Starting Tune

• Datalog Review

• Tune Revisions

• Air/Fuel Calibration

• Ignition Timing Calibration

• Torque Management Calibration

• Throttle Calibration

• Transmission Calibration

• Shift Strategy Optimization

• Remote Tuning Support

Why Tune Your 392 / 6.4 HEMI?

The factory calibration has to work for thousands of vehicles, climates, fuel qualities, and driving conditions.

Your vehicle only has to work for your setup.

Once you start adding:

• Intake

• Headers

• Exhaust

• Camshaft

• Fuel Upgrades

• Other Performance Parts

the calibration becomes just as important as the hardware.

A proper custom tune brings the entire combination together.
