The Lexus LS 500 - 420hp is a 3.5L naturally aspirated petrol engine producing 420 BHP and 600 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 450 BHP and 670 Nm — a gain of around 30 BHP (7%) and 70 Nm (12%).
This engine has limited remap suitability, with gains weighted towards torque — you will notice the difference most strongly in mid-range pulling power and in-gear acceleration. The tuning headroom is classified as limited, based on the percentage gain available from the factory output.
Considerations: Naturally aspirated engine: gains are usually limited; results vary widely.. High tuned torque: check transmission torque capacity and service history.
