Diesel Dyno Tuning
In-house diesel dyno tuning on our Mainline AWD 1200 roller dyno. We optimise your diesel engine for maximum torque, towing capacity and fuel economy — measurable gains every time.
Diesel ECU Remapping
Custom diesel ECU remaps to unlock hidden power and torque from your 4x4. We rewrite fuel injection maps, boost pressure and throttle response for real-world gains — not just on paper.
Performance Exhausts & Intakes
Authorised dealer for RedBack, Torqit and XForce. Stainless exhaust systems, DPF solutions and performance air intake kits for diesel and petrol 4x4s. More flow, more power, better fuel economy.
Transmission Cooler Upgrade
Protect your automatic transmission from heat damage with an aftermarket transmission cooler. Essential for towing, 4x4 touring and heavy-load driving — dramatically extends transmission life.
Secondary Fuel Filter
A secondary fuel filter is the best insurance against dirty diesel. We fit quality inline secondary filters to protect injectors and fuel pumps from water and particulate contamination.
Oil Catch Can
Prevent harmful oil vapour from re-entering your diesel intake and fouling the intake manifold, intercooler and throttle body. A must-have mod for any turbo diesel 4x4 used for towing or touring.
