3000NM At The Wheels! 🤯

This 2022 R620 came in already making some serious power.
480HP and 2,596Nm at the wheels from the factory. But the owner knew there was more in it, and he was right ✅

After a dyno session at HD Tuning:

Stock 🧐
480.1 HP
2,596 Nm

Tuned 🚀
601.2 HP
3007.2 Nm

+121 HP. +411Nm. That's 25% More power and 16% more torque - with the driveability and reliability you need when you're hauling serious weight aross serious distance.

Every tune we do is custom mapped to the specific engine and application. No generic files, no guesswork - just data, dyno, and results!

On the rollers and making numbers! 🔴

2023 Hino 300 817 N04C 4.0L (Manual)

This one came in as a well-kitted work truck. It left with a lot more grunt.

Stock 📉
133.9 HP
394.0 Nm

Tuned 🚀
169.8 HP
508.0 Nm

+36 HP. +114 Nm.
27% more power, 29% more torque — all figures measured at the wheels.

The Hino 300 series is a weapon of a platform, and the N04C responds very well to a proper tune. More pull from low RPM, better response under load, and real-world gains you'll feel every time you put your foot down.

If your work truck is feeling a bit flat, get in touch — we'll show you what it's capable of.

Stock to Seriously Capable 💪

2025 Isuzu NPS75-155 4HK1 (Manual)
This rig came in under-cooked from the factory. It left a different machine.

Stock 📉
90.2 HP
256.8 Nm

Tuned 🚀
178.9 HP
471.5 Nm

+89 HP. +215 Nm. 🤯
Nearly double the power, 84% more torque - all proven on the dyno. ✅

Whether you're crossing the Nullarbor loaded right up, or just need your rig to pull like it should, a proper dyno tune makes all the difference.

Diesel is what we do - light vehicles, prime movers, construction and ag machinery. If it runs on diesel, we can tune it. 🔧

Big truck. Bigger numbers. 📈

This 2016 Western Star DD15 came in with an existing tune already on it. One that had been causing the owner a few headaches. Rather than patch it up, we started fresh, and built a calibration properly around the vehicle.

Then we put it on the dyno. Because that's what we do.

Stock ✅
Power 432.8 HP
Torque 2015.2 Nm

Tuned 🔥
Power 527.5 HP
Torque 2316.9 Nm

That's a huge gain of +95 HP and +302 Nm. At the wheels. On the graph. No guesswork.

Stronger pull under load, better throttle response through the rev range, and a properly calibrated engine that's not burning fuel unnecessarily. At today's diesel prices, that matters.

The owner's words said it all. Glad he came in. Glad it's done properly.

We dyno test every vehicle we tune ✅
Light vehicles to heavy haulage, one truck to a full fleet. Bring it in and let's see what it's got.

The parts were there. The tune made them work. 💪

This 2016 Ford Ranger Wildtrak 3.2L P5AT came in already wearing some serious hardware - aftermarket intercooler, Stage 2 hi-flow turbo, and full turbo back exhaust system.
The owner did the hard work fitting it all... We did the hard work making it sing!

Before ✅
Power 153.1 HP
Torque 363.0 Nm

After 🔥
Power 202.3 HP 🚀
Torque 509.4 Nm 🚀

(All figures measured at the wheels)

A custom ECU tune to bring it all together and unlock everything that hardware is capable of. This is what happens when the tune matches the mods! ✅

Some vehicles are built for everywhere.

This one just needed the tune to match 🔥

The 2017 Toyota Landcruiser VDJ200 is legendary for a reason... it goes where others don't, carries what others can't, and keeps going when others stop. But out of the factory, it's tuned for the middle ground.

We don't do middle ground.

📊 Stock: 168.7 HP / 408.6 Nm
🔥 Tuned: 220.4 HP / 511.3 Nm

More pull on the climb. More confidence on the highway. More of everything the VDJ200 was always capable of!

But the real difference?

With the addition of our transmisson tuning, this customer will feel sharper shifts that actually match the power. Smoother, more predictable delivery through the gears.

Safe. Reliable. Dyno tested. Built for wherever you're headed next.

This is why dyno testing matters.

This 2020 Ford Ranger 3.2L P5AT auto arrived with an existing tune already installed.

Rather than assuming it was right, we put it on the dyno, measured the results, and built a calibration properly around the vehicle.

🟢 True stock
Power: 143.6 HP
Torque: 354.1 Nm

🔵 As-arrived tune
Power: 155.9 HP
Torque: 387.6 Nm

🔴 HD Tuning
Power: 179.6 HP
Torque: 479.1 Nm

The final result delivered a major improvement in torque delivery, response, and overall drivability.

This is not about naming or comparing... it’s about showing the value of proper testing, proper data, and a calibration developed for the vehicle in front of us.

Every vehicle is different.
That’s why every tune should be tested properly. ✅
