Holden Colorado 2.8L Duramax Diesel Tuning
How Much Power Can the Duramax 2.8L Gain?
2.8L 4-Cyl Duramax Turbo Diesel
Our Colorado tuning program delivers real, measurable results — validated on our in-house dyno. The 2.8L Duramax responds strongly to remapping.
A custom remap delivers meaningful gains in mid-range torque that transform real-world towing and load-carrying capability. The Duramax is a proven, durable engine that handles increased outputs reliably when done properly.

The Aussie Work Ute. Properly Built.
The Holden Colorado with its 2.8L Duramax diesel is a popular work and touring platform across Australia. It's tough, practical, and the Duramax engine is well-regarded for its reliability and tuneable characteristics.
At Stealth Installs we regularly work on Colorado and D-MAX platform vehicles at our Salisbury workshop. We know the Duramax engine well and can set your Colorado up for work, towing, or serious off-road adventures.

What We Do for Your Colorado
Proven modifications for the 2.8L Duramax platform.
ECU Remapping
The Colorado's 2.8L Duramax responds strongly to remapping, delivering meaningful gains in mid-range torque that transform real-world towing and load-carrying capability.
Intercooler Upgrades
An upgraded intercooler reduces charge air temperatures under sustained load — critical for a work ute operating in Australian heat or consistently towing trailers.
Exhaust Systems
A 3" stainless exhaust reduces backpressure from the Duramax turbo system, helping spool response and allowing the engine to extract more from the remap. Off-road DPF options available.
Catch Can Systems
The Duramax produces blow-by that accumulates in the intake over time. A quality catch can is a simple, inexpensive investment that protects the engine long-term.
Suspension Upgrades
Colorado suspension setups for work, towing, or off-road use. We build setups that handle loads and accessories without sacrificing driveability or safety.
Accessory Installs
Bull bars, canopies, trays, dual battery, winches, and lighting — we build complete Colorado work and touring vehicles suited to Australian conditions.
