Here at DPL we have created the perfect product in HGV, Truck and commercial turbo diesel engine performance upgrades. We pride ourselves in doing so without spoiling any of the principle reasons for running a turbo diesel powered vehicle in the first place and believe that key points such as their fabulous low down tractability, their reliability and of course the all important fuel economy should never, ever be compromised.

Our aim when creating our HGV, Truck and commercial turbo diesel engine performance upgrades is to gain the perfect increased power curve and fuel economy improvements yet retain all the safety parameters originally programmed into the engine management by the manufacturer so as to protect your engine and drive train from damage.

All our HGV, Trucks and commercial vehicle remaps are programmed to give a strong, linear power delivery right across the rev range.

Rest assured that we don’t just look for a torque and power peak to make the numbers look good. We aim for maximum safe improvements everywhere so the vehicle feels like it has a bigger engine.


Our power gains and improved fuel economy are achieved by very careful matching of parameters such as boost pressure, fuel delivery rates & pump timing along with adjustments to maps that electronically limit torque, throttle response and top speed. All this information in your ECU calibration file is carefully optimised to our exacting standards and then programmed back into your ECU and the vehicle comprehensively tested before we allow you to take the vehicle away.

We also offer other services as part of the remap.

For example a vehicle used for motorsport may require removal of the EGR, a DPF delete, and also benefit from having the vehicle speed limiter removed.


Our diesel tuning in Perth focuses on clearing soot from your exhaust filters. These filters are meant to reduce soot build-up from burning non-petrol fuel in your vehicle. If the filters get clogged they can damage your engine, create a fire hazard to your vehicle due to overheating, and result in a loss of vehicular power because of automatic safety features built into your vehicle’s computer system.

Having your exhaust filters regularly serviced and cleaned is the best way to ensure soot does not build up. When you bring your vehicle to us, we will check the filter to see if it needs replacing or regenerating. We will also flush your exhaust system to remove any built-up debris.

Working with a diesel truck engine can be even more complex since these engines require different components and assembly.

The differences between a gasoline engine and a diesel engine are subtle but important. One of the key ways in which a diesel engine distinguishes itself from a gas engine is that the level of air involved in the internal combustion process undergoes a much higher compression rate.

If that sounds confusing to you, just think: more pressure, more heat. How does this translate into tangible differences for a driver? For one thing, when it comes to performance, diesel engines offer a greater amount of torque than their gas engine cousins.
