The Volkswagen Polo 1.4 TDI 70hp is a 1.4L turbocharged diesel engine producing 70 BHP and 155 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 100 BHP and 245 Nm — a gain of around 30 BHP (43%) and 90 Nm (58%).
This engine scores highly for 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 high, based on the percentage gain available from the factory output.
From a technical perspective, the ECU is a Bosch EDC16 (likely), and the transmission is manual and dsg/s tronic automatics are common depending on model/engine..
Considerations: Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.
Fuel economy note: economy gains unlikely at full power; depends on driving style.
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.
