What can I expect from a 300 Series tune?

Turn every climb, tow and track into effortless adventure

The new-generation 300 Series packs serious engineering under the bonnet, but it’s held back by a cautious stock map. Our tuning frees it up with sharper response off the line, torque that comes in right when you need it, and smoother, stronger pull through every gear.

So why tune your Cruiser? To make it feel alive in every scenario, whether you’re hauling heavy loads, carving up mountain tracks, or eating up the kilometres on a cross-country run.

The real gains you can expect from a 300 Series Land Cruiser tune

Power, precision and endurance, all built for the long haul

A professional tune from Willy’s Workshop maximises your Land Cruiser’s full potential, fine-tuning power delivery, fuel efficiency, and drivability to suit the real-world challenges you face. Here’s how it makes a difference on every trip:

Instant power when and where you need it

No more lag or waiting for power to catch up. Your Cruiser lunges forward right from the get-go, hauling trailers and gear without hesitation.

Engine that keeps it cool

Add an intercooler upgrade and you’ll feel the difference. It helps cut heat soak, ease engine strain and keep things running smoother when the pressure’s on.

Effortless torque that adapts on the fly

Power flows seamlessly and adjusts to the terrain, which keeps your ride smooth and steady whether you’re navigating tight rocks or charging up steep climbs.

Options & Considerations

Get your 300 Series ready for the long haul, the rough stuff, and every adventure you throw at it

Every 300 Series has its own mission. No matter if you use yours to tackle remote tracks, tow big loads, or just cruise through the daily grind, we customise your tune to fit your drive. But that’s just the start… Check out what else we bring to the table.

Multi-mode mapping for every mission

Switch between towing, economy, or performance maps at the flick of a switch. Adapt your Land Cruiser instantly. No compromises, just the right power for the job.

Power, efficiency, or towing dominance — you decide

Want to keep temps low on steep climbs? Reduce strain when hauling? Or smooth out weekend drives? We listen, then tune your 300 Series to match your priorities.

Tried-and-tested upgrades, dialled for your 300

From GR Sport to GX, we fit high-flow intakes, upgraded intercoolers, and driveline tweaks. And tuned to your vehicle’s exact needs, not some generic setup.

Custom tunes made for your adventures

We don’t do one-size-fits-all tunes. We start with your goals, then fine-tune the ECU to boost your Cruiser’s strength, efficiency and driveability.
