The Ultimate Ford 3.5 EcoBoost Tuning Guide

Ford 3.5 EcoBoost is arguably the best F-150 engine out there in terms of towing, performance, and fuel economy. It offers 365 – 450 horsepower. However, its power may vary in the other variants of twin-turbo 3.5L V6.

A tuner can bring out 3.5 EcoBoost’s true potential and help boost its power. Read on to learn the basics of EcoBoost 3.5 tuning.


Tuning Basics for 3.5 EcoBoost V6

Tunes are one of the most popular ways to modify engines. It modifies or rewrites the engine parameters in your car’s computer, like its boost, fuel delivery, and ignition time. The turbo engines have huge potential when it comes to adding a tune.

It’s important to note the difference between a tune and a tuner. Tune is the software that modifies your car’s engine parameters. Whereas, a tuner is a device or a person that tunes your engine. So, a 3.5 EcoBoost tuner could refer to a device or a person who tunes the engine.


Ford EcoBoost 3.5 Tuning Benefits

The biggest benefit that comes with tuning for EcoBoost 3.5 is the obvious horsepower gain. However, there are other secondary benefits which include:

  • 70 – 120+wtq
  • Improved fuel economy
  • Improved throttle response
  • 50 – 100+whp


Many 3.5 EcoBoost tunes offer gains of around 50-100whp without other mods. The torque to the wheels can be improved to 70-120. Higher-end power gains will be for 3.5L V6 running on race gas, E85, or 93 octane blends.


How to Tune Your 3.5 EcoBoost?

You can tune your engine either with a custom flash tune or with off-the-shelf standardized tuners like the famous JB4 Piggyback Tune.


JB4 Piggyback Tune for 3.5 EcoBoost

The piggyback is easy to plug and install. It comes with seven tuning maps that you can switch between at any time. It takes around 2 seconds to change the map. The JB4 is almost impossible to detect if it’s still in the warranty and you uninstall it before visiting the dealer as the ECU shows 100-percent stock data when the piggyback tunes the signals. This Ford 150 EcoBoost costs $529.


Custom Tuning the EcoBoost

Custom tuning is still an option with flash tunes. All the EcoBoost tuners feature standard maps that are pre-installed on the tuning device. But all 3.5 EcoBoost aren’t the same. And as some people drive it at different altitudes and elevations, the tuners can’t specifically tune every engine for its unique requirements. The standard maps are generic and supposed to work with every 3.5 EcoBoost engine.

Custom tuning can offer huge performance improvements and other benefits if done correctly. The technician will dial the tuner that’s specific to your elevation, truck, and other conditions. The process may take some time to tune perfectly, but eventually, it allows you to bring out your engine’s full potential.
