About this remap
Land-Rover Defender 2.2 TD4 122 hp Stage 1 — what changes
The Land-Rover Defender 2.2 TD4 122 hp (2012–) leaves the factory at 122 BHP and 361 Nm of torque. Manufacturers deliberately detune this engine to separate it from more expensive variants in the range — a Regal Tuning Stage 1 calibration safely recovers that headroom through the ECU alone: no hardware changes, no dyno risk, fully reversible.
Fuelling, boost pressure, ignition and torque limiters are optimised within the safe tolerances of the 2.2 TD4 122 hp powertrain (diesel). The result is 158 BHP and 485 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
