How Engine Tuners Work

A 6.4 Powerstroke tuner helps you optimize the diesel engine’s performance. You can make adjustments to the power output, fuel consumption, and more, depending on what features the tuner offers. Basically, the programmer tells your Ford truck engine how to respond under certain conditions. It doesn’t make any permanent changes and can be quickly reverted.


Benefits of Tuners & Programmers For Ford Trucks

When you find the best diesel tuner for 6.4 Powerstroke, you receive multiple benefits. First, you can increase the performance to gain more horsepower or torque. Secondly, it’s possible to alter the settings to save fuel. When you increase the fuel economy, you save money every time you visit the pump.


How To Choose The Right 6.4 Powerstroke Tuner

Compatibility

What is the best tuner for 6.4 Powerstroke? Obviously, it won’t be the same tuner as one used on a gasoline-powered engine. Instead, you need to purchase the tuner that is capable of modifying your diesel Powerstroke engine. Most brands list the compatible engines right on the product description page.

Ease of Set-Up & Use

Are you an expert in setting up diesel tuners? If not, you want to find a model that is considered plug and play. Many diesel tuners have simple setup instructions and will walk you through the process right on the screen. Read through the 6.4 Powerstroke DPF tuner reviews to see what other customers thought.

Power Levels

Your tuner will likely come with pre-set power levels that make customization of your engine simple. You can choose options for towing, fuel economy, or additional performance. Read through the description to see what power levels are offered to ensure they will match your needs. If you want to fine-tune some settings, look for a model that lets you input your own parameters.

ECM Download Time Frame

Some machines simply work faster than others. Typically, the more expensive diesel tuners are also going to be the units that respond the quickest. Read through the reviews to see how fast the tunes take effect. After all, it makes no sense to be sitting around for minutes, waiting for the changes to occur.

Storage

When you customize the performance options, it helps if the unit has storage capability. Otherwise, you will have to figure out the setting again when you want to use it in the future. Look at how many settings can be saved with your particular tuner, especially if you plan to use it for varying functions.

Monitor Size

If you are low on space, you might prefer to use a unit with smaller monitor size. If you will be making adjustments while on the go or you want real-time data, the larger screen might be best. You can also look for additional features, such as touchscreen capability, but these extras will add to the price.

Data Monitoring Capabilities

Some diesel engine tuners also provide access to valuable system data. If you want to monitor temperatures or other vital information, you will want to splurge on one of these units. Furthermore, you can find options to read and delete DTCs. If you plan to work on your diesel truck yourself, this option is invaluable.

Versatility

If you only want an engine tuner to increase your towing power, you won’t need an option with lots of settings. If, however, you desire a diesel tuner that monitors data, reads trouble codes, and can assist you in setting multiple tweaks, you will want a machine with maximum versatility.

All About Powerstroke Engines

Powerstroke engines have been around since 1982. The first model was a 6.9L Indirect Injection engine that output 170 horsepower and 315 pound-feet of torque. In 1994, the iconic 7.3-liter Powerstroke was released.

This model showcased an all-new turbocharger and direct injection. Then, in 2003, Ford released the 6.0-liter Powerstroke with a huge reduction in emissions. But, the big news came with the 2008 model lineup and the release of the 6.4L Powerstroke. It was the cleanest engine to date and features twin turbochargers.

In 2011, we also received the 6.7L Powerstroke engine. This is a light, powerful, and efficient power plant. Since then, we have also seen the introduction of a 3.0 and 3.2 Powerstroke


Engine Tuner Compatibility

You can't use an engine tuner on the wrong truck, or it simply won't make the necessary adjustments. That's why you must check the compatibility before making a purchase. As you search for the 6.4 Powerstroke tuner for DPF delete, read the description to ensure it works with your model. Even the best tuner for 2008 6.4 Powerstroke might not work on your new truck, so pay close attention to this detail.


Installing a 6.4 Powerstroke Engine Programmer

Most of the 6.4 Powerstroke EGR and DPF delete tuner options come with comprehensive instructions for installation. You will plug the equipment into your OBDII port and follow the prompts.

Make sure you also mount the screen in a convenient location. If you want a visual understanding of the installation, you can watch this video that highlights the steps to use an H&S Mini Maxx tuner for 6.4 Powerstroke.


People Also Ask (FAQs)

What are the common issues of 6.4 Powerstroke engines?

The 6.4L Powerstroke production only ran for a few years, but the engine did see its share of problems. These pickups featured weak fuel economy, DPF clogging, and engine oil cooler clogs. 

Can tuners check DPF real-time status?

Some of the more advanced models can check DPF in real-time, but you will pay more for this function.

What does DPF regeneration mean?

Diesel particular filter regeneration occurs when the trapped particulates heat up and combust. This action turns the particulates to ash. Then, the built-up soot is removed as carbon dioxide. It occurs in three ways: forced, passive, or active. 

What is the maximum amount of horsepower that I should add to my engine?

You can add as much power as your engine tuner will allow, but you must know that the increase in power also adds more heat and pressure to the cylinders. When you make these modifications, you add more stress to the motor. That's why you might require forged pistons, cranks, or rods to handle the extra stress.

Are these programmers made for both gas and diesel engines?

You can find engine programmers to work with both gas and diesel engines, but not typically the same model. You won’t want to use your Spartan tuner for 6.4L Powerstroke on your wife’s Honda SUV.

Will I get better mileage with these tuners?

If you set up the engine tuner for maximum fuel economy, you can expect to receive better gas mileage numbers. However, if you alter the engine for additional performance, expect your fuel economy to drop.

Can engine tuners void the car warranty?

Most of the time, your engine tuner will not void the warranty. Read through the company’s stance on vehicle warranties before purchasing. Even still, you might wish to reset back to stock settings and remove the equipment before taking your pickup to the shop.


Conclusion

For the most part, we recommend the Edge Products 85401 CTS2. Yes, it is on the pricey side, but it is compatible with many diesel Ford motors and supplies a multitude of useful settings.
