*Results depend on your vehicle and setup. These figures represent typical outcomes from a professionally completed custom dyno tune.
Your vehicle left the factory with the handbrake on.
Manufacturers tune engines conservatively — for global emissions compliance and market segmentation, not for Australian conditions or how you actually use your vehicle.
​
The result? Sluggish throttle response, more fuel stops than necessary, and a diesel that feels like it's always half-asleep.
A custom ECU remap by OSP recalibrates your engine's control unit to unlock the power, torque and efficiency your diesel was actually built for.
With diesel sitting above $2.40/L, a 10–15% fuel saving on a high-km ute or 4WD can recover the cost of the tune within 12–24 months.
For tradies and farmers doing serious kilometres, the maths is simple.
