The Vauxhall Astra 1.7 CDTi 110hp is a 1.7L turbocharged diesel engine producing 110 BHP and 260 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 150 BHP and 330 Nm — a gain of around 40 BHP (36%) and 70 Nm (27%).
This engine scores highly for remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
