2.8L – Delco E98 ECU – EGR + DPF

The Challenge

In this article, we explore how tuning the Holden Trailblazer can transform this SUV into a true towing powerhouse. To illustrate, we’ll take a look at a 2019 Holden Trailblazer that we have fine-tuned. The customer was seeking to improve the Trailblazer’s towing capabilities. Here at Alt Tune, we have the skills to give the customer what they dream of.

The 2019 Holden Trailblazer is a versatile and capable midsize SUV known for its robust performance and impressive towing capacity. However, for those who regularly tow heavy loads or crave a more confident and efficient towing experience, tow-tuning offers an exciting opportunity.

The Solution

First, we took a look at the Trailblazer, making sure it was fit to be tuned. We afterwards decided to use Alientech KESS3 to flash a towing tune. With a tow tune the focus is on optimizing the engine’s settings to increase towing capabilities. This is done by fine-tuning parameters like fuel injection timing, torque delivery, and transmission settings.

Tuning the Holden Trailblazer increases towing capacity, enhances torque, increases power and improves fuel efficiency, This means that you can tow heavier trailers, boats, or campers with greater ease and confidence. Whether you’re hauling equipment for work or embarking on a family camping trip, tow-tuning ensures that your Trailblazer is up to the task.
