Lexus offers a diverse engine lineup — approximately 9% diesel and 86% petrol across 22 variants in our database. Both fuel types respond well to Stage 1 remapping, with turbocharged diesel engines typically delivering the largest gains in both power and torque.
Across the Lexus range, Stage 1 remap gains typically fall between 9 and 55 BHP (averaging 22 BHP) and 18 to 110 Nm of additional torque (averaging 40 Nm). Turbocharged variants see the largest improvements, while naturally aspirated engines benefit from refined throttle mapping and ignition advance.
A Stage 1 ECU remap optimises your Lexus's factory software to unlock its full potential — no hardware changes required. Here are the typical gains across the range.
