What is diesel tuning?
Modern diesel engines are run by computers called ECUs—Engine Control Units. These ECUs manage nearly every aspect of how your engine runs, from when and how much fuel is injected, to controlling the turbo boost and managing the throttle response.
Diesel tuning involves reprogramming this computer to adjust those key settings. This allows you to optimise things like fuel injection timing, increase turbo boost pressure, and fine-tune throttle response to get better power, improved efficiency and a smoother driving experience.
At Willy’s Workshop, we provide a variety of expert tuning services to get the most out of your vehicle.
Multi-mapping
Switch between different tuning setups tailored for various driving conditions, giving you the perfect performance no matter where you drive.
Model Upgrades
Upgrade your engine with parts and software designed specifically for your vehicle to boost overall performance.
ECU Remapping
Fine-tune your engine to boost power, improve fuel economy and enhance throttle responsiveness.
Transmission Tuning
Smooth out gear changes and improve power delivery by fine-tuning your transmission.
Dyno Tuning
Measure and adjust your engine’s performance on a dynamometer to achieve precise power and efficiency gains.
The benefits of diesel tuning on the Sunshine Coast
At Willy’s Workshop, we specialise in fine-tuning diesel engines to get every bit of power out of them, all while making sure they can handle the Sunshine Coast’s unique mix of coastal roads and rolling hills.
Increased torque and engine output
Through ECU recalibration, we optimise fuel injection timing, boost pressure, and torque limits to deliver measurable increases in torque and horsepower. This translates to stronger acceleration, improved load pulling, and greater capability for towing caravans or trailers
Optimised fuel efficiency and combustion
Our diesel tuning refines your engine’s combustion cycle by adjusting injector pulse and air-fuel ratios, which reduces fuel consumption without sacrificing performance.
Smoother shifts and less turbo lag
We don’t just work the engine. We fine-tune transmission shift points and torque management to minimise turbo lag and deliver seamless acceleration.
Keep your engine healthy and reliable
We know performance is great, but your engine’s long-term health matters more. Our tunes boost your vehicle without pushing it too hard, so your diesel stays reliable and strong, kilometre after kilometre.
Performance Tuning Packages
At Willy’s Workshop, our diesel tuning service takes your vehicle’s performance to the next level, giving you a smoother, more responsive drive that matches how you use your vehicle every day.

Mercedes Sprinter. Turbos replaced, ECU replaced, ECU tuned, battery replaced. 16 times returned to fix it from going into limp mode. $8,920 out of pocket. Took it elsewhere. Fixed with a $80 waste gate vacuum valve! Willys had no idea how to fix it. Made contact 3 times after with Willys...washed their hands of it. I refitted old turbos, as nothing wrong with them and sold new turbos to gain some costs & to prove Willys are a disgrace.

Beware Beware Beware!
Very disappointed with the work done on my car. It went in to fix a coolant leak and tune and was returned to me with a hole in the radiator and slashes to my steering wheel. After the radiator was repaired, fuel was spraying all over the engine bay. Now the original work is leaking coolant. My wife has been stranded on the Kawana Way twice with low coolant warnings less than 3 minutes after picking up the vehicle.
The tune is great!
Even though I was promised that the steering wheel would be repaired this hasn’t happened. In addition, I was told a radiator from Audi was $2900 however when I called Audi an OEM radiator from Audi was $900 retail, I was charged $1100 for an aftermarket one.
The most disappointing was the communication, with lie after lie being told. My wife was told to “sell the car and get a Camry if you’re worried about the cost.”
DO NOT TRUST these people and don’t allow them to work on your car.
I have given them ample opportunity to address these issues but there has been no willingness to rectify the problems. $6000 plus later I am paying Audi to fix the car.
You have been warned. Please don’t do this to yourself.

Anthony at Warana displayed excellent knowledge and explained the process well.
Invoiced as quoted even though the job took longer than expected due to rusted nuts.
I offered to pay more but he declined.
Extremely pleased with the overall experience.
Top work!

Sent it in for a tuning package on Monday, was told will see it Friday; recieved it Tuesday same week. Had a few things tweaked as well so hopefully I will not see some pestering problems resurface. Communication was clear and timely. Will come back again for a service.

FAQs
Got questions about diesel tuning on the Sunshine Coast? We’ve tuned it all, from beach rigs to tow beasts, and these FAQs cover what you need to know.
Can you remap diesel utes for Sunshine Coast beach driving?
You bet! We can optimise your diesel tune for the unique demands of beach driving, whether it’s soft sand at Double Island or long stretches near Noosa North Shore. We fine-tune for better low-end torque and instant pedal response, so you won’t be left bogged or over-revving.
Will my tuned vehicle be suited for mountain drives to Montville or Maleny?
Absolutely. We can tune your diesel for smoother gear shifts, stronger uphill pulls and more control on descents, perfect for tackling winding climbs or weekend trips through the Hinterland.
Is diesel tuning safe for towing caravans or trailers through Sunshine Coast hills?
Yes — when done right. Our custom tunes improve torque delivery and engine efficiency under load, making it safer and easier to tow up steep inclines like Obi Obi Road or Bald Knob Range.
How does diesel tuning affect fuel economy on Sunshine Coast highway runs?
With the right tuning, you’ll likely see improved fuel efficiency, especially during consistent cruising along the Bruce Highway or Sunshine Motorway. Power where it counts, efficiency where it matters.
Can you adjust my tune for different driving styles — like weekday commuting vs weekend getaways?
Absolutely! we can customise your tune based on how and where you drive. From daily runs through Maroochydore traffic to long hauls out past Gympie, we’ll set your diesel up to perform how you need it to.
Can you retune after I add other upgrades like an exhaust or snorkel?
Definitely. In fact, a re-tune is often needed to get the most from new mods. Whether you’re adding an aftermarket intercooler, snorkel, or full exhaust system, we’ll recalibrate to make sure everything is firing on the same wavelength.
