The Land Rover Defender is built for ultimate utility, but factory restrictions and emissions systems consistently compromise its power delivery and long-term reliability.
This Defender came into our workshop for a mechanical and electronic upgrade. We addressed the exhaust restrictions first by replacing the factory setup with a custom stainless steel downpipe, drastically improving gas velocity and dropping thermal loads.
To safeguard the engine against future mechanical failures and inefficiencies, we performed a complete EGR and DPF code out. We then finalised the build with ATM's Stage 1 software calibration, optimizing the parameters to extract maximum efficiency and power from the unrestricted hardware.
The outcome is an immediate, definitive transformation: a massive surge in low-down torque, crisp throttle response, and a powertrain engineered for absolute reliability under any conditions.
Stop settling for compromised factory limitations.
