Stage 1 remap estimates for 323 engine variants across 25 models
Browse All Models ↓Vauxhall offers a diverse engine lineup — approximately 54% diesel and 46% petrol across 323 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.
Around 84% of Vauxhall engines in our database feature forced induction, making them excellent candidates for remapping. Across the range, Stage 1 gains typically fall between 5 and 80 BHP (averaging 30 BHP) and 10 to 170 Nm of additional torque (averaging 56 Nm). These gains come from optimising boost pressure, fuelling, and ignition timing — all within the engine's mechanical tolerances.
With an average suitability score of 7/10, Vauxhall engines are generally very well-suited to Stage 1 remapping. This means a professional remap can unlock meaningful performance gains while staying well within the engine and drivetrain's design limits.
A Stage 1 ECU remap optimises your Vauxhall's factory software to unlock its full potential — no hardware changes required. Here are the typical gains across the range.
