About this remap
Mercedes ML 63 AMG (5.5T) 525 hp Stage 1 — what changes
The Mercedes ML 63 AMG (5.5T) 525 hp (2011–) leaves the factory at 525 BHP and 700 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 63 AMG (5.5T) 525 hp powertrain (petrol). The result is 651 BHP and 921 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
