About this remap

Lexus IS 220d 174 bhp Stage 1 — what changes

The Lexus IS 220d 174 bhp (2005–2012) leaves the factory at 174 BHP and 400 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 220d 174 bhp powertrain (diesel). The result is 216 BHP and 457 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
