About this remap

Nissan Navara 2.5 DCi 133 bhp Stage 1 — what changes

The Nissan Navara 2.5 DCi 133 bhp (1998–2004) leaves the factory at 133 BHP and 304 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 2.5 DCi 133 bhp powertrain (diesel). The result is 156 BHP and 358 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
