Landcruiser 300 Series Tune

Suits the 3.3 litre twin-turbo V6 diesel, across all 300 Series models.

More from the 300 Series

The 300 Series is the most capable Landcruiser Toyota has built. Its 3.3 litre twin-turbo V6 diesel was a big step forward from the V8 it replaced, but it still has plenty left to give. Our tune draws more out of it, so the 300 tows harder, responds faster and handles the long kilometres with less effort.

Developed in our own 300 Series

Our tune wasn’t developed on a dyno and left there. It’s the result of serious real-world testing in our own 300 Series, across daily driving, long-distance touring, stop-start traffic and towing our caravan.

Power and torque where you’ll use it

The tune adds strong power and torque across the rev range, with the biggest improvement low and in the midrange, where the 300 spends most of its time. Throttle response is sharper, overtaking needs less planning, and long grades are far easier with a full load or a van behind it.

Torque delivery is strong and clean, with no surges or flat spots, so the extra performance feels natural rather than forced.

One calibration for everything

There’s no switching between maps. One fully optimised calibration covers daily driving, heavy towing and long-range touring, whether the vehicle is loaded or empty.

Done the way Toyota does it

We reprogram the engine control unit through the OBD port, the same way Toyota programs it. There are no chips, piggyback modules or cut wires, and nothing comes out of the vehicle. It’s one remap that makes your 300 stronger and more capable everywhere.

What’s Included

Pre-Tune Health Check & Baseline Dyno Run
We assess your engine under load, record its data and measure its current power and torque. If we find an issue, you’ll hear about it before we touch the tune, not after.

Fault Code Scan
We scan for stored and pending fault codes before any tuning starts.

Engine Remap
A calibration tailored to your vehicle, delivering more power and torque with smooth drivability.

Data Logging & Dyno Testing
We monitor how your engine responds under load throughout the tuning process and verify the results on the dyno.

Post-Tune Road Test
Every vehicle is road-tested before handover to check how it drives beyond the dyno.

Before & After Dyno Printout
You receive a printout showing your power and torque before and after tuning, so you can see the results.

Please note

• Before and after figures are engine figures. They are calculated by applying the percentage gain achieved on our dyno to the manufacturer’s quoted power and torque, and are based on vehicles running standard wheels and tyres. They are provided as a guide only.
• Results vary between vehicles depending on kilometres, engine condition, modifications fitted, and wheel and tyre size. The before and after dyno print-outs supplied with each tune show figures measured at the wheels, which will be lower than engine figures. Larger or heavier wheels and tyres will reduce measured figures further.
• Vehicles must be in good mechanical condition prior to tuning. Increases in power on high-kilometre engines are assessed case by case.
• Additional parts and labour may be required where worn or faulty components are identified, and these will be quoted before any work proceeds.
• Prices are subject to change without notice. Images are for illustration purposes only.
