Our custom ECU remapping and multi-mapping solutions for the GDJ70 Series represent the pinnacle of diesel tuning technology. Choose between our single map tune for consistent, enhanced performance, or opt for our exclusive multi-map solution that puts control at your fingertips. The multi-map feature lets you switch between different tuning profiles on the fly – from an economical daily driving map to a high-performance setting when you need maximum power.
Maximise your GDJ70’s off-road capability with our Easy Lock ECU lock-up solution. This upgrade transforms your vehicle by allowing you to engage the rear differential lock with the simple press of a button. Unlike factory systems, Easy Lock provides instantaneous engagement when you need it most, giving you complete control in challenging terrain.
Transform your GDJ70’s performance and sound with our premium 4-inch exhaust system, available in both DPF-back and turbo-back configurations. The DPF-back system offers an optimal balance of improved flow, while our turbo-back option delivers maximum performance gains by reducing exhaust restrictions from the turbo all the way to the tail pipe.
Optimise your GDJ70’s air intake system with our high-flow 4-inch air box upgrade. Engineered specifically for the harsh Australian conditions, this system provides superior protection against dust ingress into your engine while significantly improving airflow.
Improve your GDJ70’s off-road and capabilities with our premium snorkel upgrade. This essential modification raises your engine’s air intake point well above dust level and bonnet height, ensuring clean air delivery even in the most challenging conditions.
