Opel Insignia 2.8 OPC V6 Turbo 325hp Remap

The Opel Insignia 2.8 OPC V6 Turbo 325hp is a 2.8L turbocharged petrol engine producing 325 BHP and 435 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 360 BHP and 550 Nm — a gain of around 35 BHP (11%) and 115 Nm (26%).

This engine has moderate 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 moderate, based on the percentage gain available from the factory output.

Considerations: Turbo petrol: fuel quality and cooling can influence repeatable performance.. High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.

All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
