Buick offers a diverse engine lineup — approximately 6% diesel and 94% petrol across 50 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 Buick range, Stage 1 remap gains typically fall between 5 and 65 BHP (averaging 23 BHP) and 15 to 130 Nm of additional torque (averaging 42 Nm). Turbocharged variants see the largest improvements, while naturally aspirated engines benefit from refined throttle mapping and ignition advance.
Buick engines have an average suitability score of 5.3/10, indicating good potential for Stage 1 remapping. As always, results vary by engine — check individual suitability scores to find the best candidates in the range.
A Stage 1 ECU remap optimises your Buick's factory software to unlock its full potential — no hardware changes required. Here are the typical gains across the range.
