Unlocking & Elevating Performance: RG Series 2 Colorado

At Ultimate Diesel Tuning, we recently had the pleasure of working on a 2019 RG Series 2 Colorado. This vehicle, having clocked over 50,000 kilometers, underwent a custom dyno tune along with an on-car chemical soot clean to ensure the manifold was in top condition for optimal performance.

Pre-Tune Inspection

Before any tuning takes place, we conduct a comprehensive pre-tune inspection. This step is crucial to confirm that the vehicle is mechanically sound and ready for the custom dyno tuning process. For the owner of this Colorado, the goals were clear: enhance drivability while increasing power and torque, especially since it tows around 3 tonnes.

Equipped with various modifications, including a front bar, 32-inch tyres, a suspension lift, rock sliders, and a stainless steel snorkel, this Colorado presented unique tuning considerations.

The Custom Dyno Tuning Process

Our custom tuning procedure begins with power runs on our all-wheel drive dyno in the vehicle’s standard form. This initial run establishes baseline power and torque figures at the wheels, allowing us to understand the starting point for each vehicle, as every engine is different. During this phase, we also verify that the engine is operating correctly, with no underlying mechanical issues. Once confirmed, we proceed with the custom dyno tune. Our tuning process involves recalibrating the software within the vehicle’s factory ECU. Using specialized software, our engineering team adjusts numerous engine control parameters, including torque limiting, desired torque, fuel injection maps, boost control, and more. With the aid of our dyno, we can accurately test these software changes for each individual vehicle, logging engine performance data after each revision. This iterative process continues until we achieve optimized power and torque based on the vehicle’s intended use. It’s a truly customized tuning experience!

Impressive Results

After completing the custom dyno tune on the RG Colorado, we were excited to share the results. Initially, the vehicle produced:

  • 110 Kilowatts of Power
  • 396 Newton Meters of Torque at the rear tires.

Post-tuning, considering its heavy towing capacity, the figures improved to:

  • 138 Kilowatts of Power
  • 486 Newton Meters of Torque!

This represents a remarkable increase of 26% in peak power and 23% in peak torque. Not only did we meet the owner’s expectations for improved performance, but the custom dyno tune also transformed the driving experience entirely.
