Engine Remapping, Chip Tuning, ECU Remaps

---

Our maps at Onyx Performance are proven time and time again as reliable and effective. Even though we can offer incredible gains in power and torque, we also believe in safe and sensible tuning - that’s why our customers return time and time again. We offer a lifetime warranty against any software malfunctions.

Our software is developed on our state of the art 4WD Dyno handling vehicles with over 1500hp.

Before carrying out any tuning we at Onyx Performance always carry out a full diagnostic health check to ensure the vehicle is in the correct state of health and no current engine issues are present including boost leaks via a smoke test. We believe that drivability and reliability is as important as performance and therefore when you choose to tune with Onyx Performance you can be confident that your vehicle is in safe hands.

Increasingly popular with rising fuel prices, we recalibrate the ECU data to improve fuel efficiency. The increase in torque will allow less gear changes and accelerator pedal movement thus resulting in improved MPG and drivability.

Designed for a standard and unmodified vehicle with no hardware upgrades. A Stage 1 Remap increases power and torque while also improving fuel efficiency on a diesel. Removes flat spots and gives a more responsive drive without compromising reliability. Additional features are also available under our 'services' menu. 

Bigger increase in power and torque than a Stage 1 Remap, efficiency will still improve but not as dramatically as a Stage 1 Tune. Often hardware upgrades are required before a Stage 2 Remap can be applied such as a Decat, Induction Kit, Bigger Intercooler etc. Removes flat spots and gives a more responsive drive without compromising reliability. We offer Stage 2 packages, find them here.

Up-rated hardware will be required, the numerous hardware additions require a fully bespoke remap carried out on our rolling road where parameters can be monitored in a safe and reliable way. Please contact us with your mod list and we can provide a custom quote and offer advice on the required hardware upgrades. Remember we carry out all engine modifications and live ECU tuning in-house. 

This service is strictly sold as an off-road use only product, driving your vehicle on the road with this service could result in prosecution.
