The advantages of 4×4 diesel tuning

Tuning your 4×4 is about so much more than just adding extra power to your ride. It’s about getting the best possible performance in every situation. At Willy’s Workshop, we use advanced diagnostics and precision adjustments to bring out the best in your 4×4. Here’s what you can expect:

More power, more control
We adjust your ECU and refine the air-fuel ratio to increase horsepower and torque, giving you quicker acceleration, sharper handling, and the confidence to tackle any terrain.

Better fuel efficiency
Through custom ECU mapping and airflow improvements, we help your engine run more efficiently—meaning fewer trips to the pump and more savings in your pocket.

Stronger towing capability
By increasing torque output and fine-tuning gear ratios, we make sure your 4×4 can handle heavy loads with ease, whether you’re towing a trailer or hauling gear.

Smoother ride
We optimise throttle response and transmission shifts to eliminate engine lag and harsh gear changes, giving you a more comfortable and controlled drive.

Willys workshop Professional, honest, and knows his stuff"

Took my truck mercedes actros MP5 to get things resolved.

Couldn't be happier with the service.
They went above and beyond, spent extra time
making sure everything was perfect before
handing it back. You can tell the team at willys workshop sunshine, really cares
about doing things properly, not rushing it
out the door.

Communication was great the whole way
through, explained what he was doing and
kept me updated. Truck runs smoother and
stronger than ever - drives like a
completely different machine.

If you want someone who actually
understands modern trucks inside and out,
this is the guy. Hard to find this level of
dedication.
Thanks to the team at willys workshop and a special thanks to Anthony, your a bloody legend mate.

FAQs

Got questions about logbook servicing? Our FAQ’s have the answers. We’ll break it down and give you the full picture on how regular servicing keeps your diesel running smooth, reliable, and in top condition.

How long does 4x4 tuning take?

We aim to get you back on the road as quickly as possible. Most tunes can be done in a few hours, but we’ll always let you know what to expect before starting the work.

Can tuning improve my fuel efficiency?

Absolutely! Our Eco Tune refines your 4×4’s fuel use, helping you get more out of every tank without sacrificing power. It’s the best of both worlds.

Is tuning safe for my 4x4?

You bet! At Willy’s, we take extra care to ensure every tune is spot on. Using the best tools and techniques, our team makes sure your 4×4 not only performs at its best but does so safely and reliably, whether you’re hitting the road or tackling the toughest trails.

Do I need to tune my 4x4 regularly?

Getting your engine tuned is usually only done once. However, if your requirements change, you’re no longer looking for torque and want to go for more fuel efficiency or if you’re looking to tweak the power profile of your vehicle, then a revision tune may be required. Tune adjustments, like this, are cheaper than a full tune. Get in touch if you have any questions.

Can you tune any 4x4 model?

Yep! Whether you’re driving a classic or a new model, we can fine-tune your 4×4 to make sure it’s running at its best. If you’re not sure, just give us a call and we’ll chat about what we can do for you.
