Towing Upgrade – Diesel Torque Tune for Towing and Touring

Loaded up with a caravan or boat, most factory diesels run out of pull down low. You drop a gear on every rise, the auto hunts between gears, and the engine works hard on a long climb. A towing tune reshapes fuelling and boost through the low and mid rev range so the vehicle holds a gear instead of chasing one. We do them at Oxley and Warana, on the dyno, set around the weight you actually tow.

Diesel tuning that works as hard as you do

Willy’s Workshop specialises in diesel tuning. Tunes are written for the vehicle in front of us and checked on the dyno, so the extra torque sits low and mid range, where a load actually pulls on the engine.

What is a Towing Tune?

A towing tune rewrites the engine’s fuel and boost maps to build torque in the low and mid rev range, which is where a heavy load sits. Our diesel mechanics set it around your rig, your load and how you drive, so you get:

Increased torque for better pulling power

Enhanced engine response on inclines

Safer, more confident towing and touring

Smoother acceleration under load

Reduced gear hunting and strain on the drivetrain

From highway hauls to mountain passes, our towing tunes make sure your vehicle stays strong, stable, and efficient, no matter what you’re pulling.

Why Choose Willy’s Workshop?

Towing vehicles spend their lives near the top of their load rating: heavy van behind, gear in the tray, long climbs in summer heat. That changes what a tune has to do. We build torque in the range you actually tow in, and keep exhaust gas temperature and boost inside safe limits rather than chasing the biggest number on the sheet.
We tune diesels every day at Oxley and Warana. Tell us what you tow, how heavy it is and where you drive it, and the tune gets set around that.

Diesel Tuning Specialists

Proven results for towing and touring setups

Data-driven performance

Every tune comes with dyno results. You will feel the difference with a load on, and the sheet shows what the engine actually did, so the change is measured rather than claimed.

Locally Owned & Operated

Two Queensland workshops: diesel tuning Brisbane (Oxley) & diesel tuning Sunshine Coast (Warana).

What our customers have to say

Sorted out issues with my Ford Everest

The guys at Willy's sorted out issues with my Ford Everest. Friendly staff and fast turnaround, couldn't recommend them enough

L Luke Madden

Couldn’t be more impressed with the workmanship from the guys.

New to the coast and chose Willys workshop to do a tune and service on my Range Rover Evoke. Couldn't be more impressed with the workmanship from the guys. More power and better fuel economy, great staff and will continue to use. Highly recommend

J Jarrod Humm

Would happily recommend this workshop.

Frequently asked questions

What is a towing tune?

A towing tune is a custom performance upgrade that maximises torque output in the low to mid RPM range, which is where towing demands it most. We fine-tune your engine's parameters around your towing needs, so you get better pulling power, stronger engine response on inclines and smoother acceleration under load.

Will a towing tune improve my fuel economy while towing?

It is one of the gains towing customers notice. A towing tune lets you maintain speed with less effort on hills and highways, so the engine is working less hard for the same job and fuel economy while towing improves.

Is a towing tune easier on my transmission?

That is the intent. More torque low in the rev range means reduced gear hunting and less strain on the drivetrain, plus lower RPM torque for easier towing from a standstill. Our towing tunes are built to deliver less wear on your transmission and clutch.

Which vehicles do you tune for towing and touring?

All the major diesel towing and touring vehicles. 4WDs and utes including the Toyota LandCruiser and HiLux, Ford Ranger, Isuzu D-MAX, Nissan Navara and Mitsubishi Triton, SUVs including the Prado, Everest, Pajero and MU-X, plus vans, service vehicles, trucks and towing rigs.

Do I get proof of what the tune gained?

Yes. We provide dyno results for every tune, so alongside the difference you feel on the road you get hard numbers for the gain. Both Queensland workshops do this work: Oxley in Brisbane and Warana on the Sunshine Coast.
