Industry Pioneer
As an industry pioneer, we’ve forged a reputation based on excellence, experience and trust. Our clients know we will expertly care for their valuable vehicles and machinery.
Here’s what some of them have to say…
The outcome was outstanding
"We've got a 162 hp Valtra tractor...we decided to go ahead with a modification and the outcome is outstanding. I just can't believe we're using the same tractor. Our diesel consumption is way back and rather than running the engine at 17-1800 rpm, we've been able to drop it back to 17-1800 rpm and several gears higher. Not only is the tractor running far more sweetly, but it's also a lot easier on the operator and the gear as well."
Lloyd Lowe, Farmer
Increased hp & torque by 30%
“I run large tractors, built out of Germany – 300 hp. Since remapping it's made the business a lot more efficient in terms of covering the ground quicker – they've increased hp & torque by 30%.”
John Wilson, JP Contracting
What makes DPS different to the rest?
Our experience and expertise
We are proud to be a pioneer of the industry. With over 18 years of knowledge and experience behind us, it’s fair to say that we know diesel engines inside-out! We will tune or modify your engine expertly and safely. Your valuable engine is safe in our hands.
We modify your ECU software here in NZ
This is in contrast to most other diesel tuning companies, who send it overseas to be modified. DPS clients gain two important benefits from having their modifications done in NZ:
Firstly, we understand the conditions you drive your diesel in because we're local. So we modify your software specifically for NZ’s unique climate and conditions.
Secondly, the software changes have been made at the DPS Head Office in Matamata. So our Diesel Technicians know what those modifications are. They have an in-depth understanding of the task ahead. They can install the updated software correctly and safely, without risking costly damage to your engine.
Each of our nationwide agents owns his own tractor dyno
That means we can test your tractor on-farm, by measuring hp and torque before and after tuning. So we can supply hard data that verifies the improvements we’ve made to your engine. Dynos are a significant outlay for our agents, but it’s a mark of how seriously they take their commitment to clients. All our agents have strong backgrounds in working with agricultural machinery.
