Remap, fueling, boost and the hardware the Duratorq actually needs. No suspension, no wheels — just the 136 PS common-rail and what a sensible file does to it.

The only remap most Mk2 2.0 TDCi cars should run. Sydney rolling-road example on a stock 100 kW car: 79 kW to 98 kW at the wheels (+24%) and 320 to 371 Nm at the engine. UK files often quote 180 PS / 375 Nm at the flywheel. Same job: more mid-range, same turbo, same clutch if it is healthy.

Map tables
| Table | Factory | This map |
|---|---|---|
| Torque limiter | Capped ~320 Nm | Raised into the mid-370s, smoothed |
| Driver-wish / IQ | Conservative requested fuel | More mg/stroke in the mid-range |
| Rail pressure | Factory ceiling | Modest lift, still inside injector spec |
| Boost / VGT | Laggy below 2,000 rpm | Actuator mapped for earlier boost, stock turbo |
| Smoke limiter | Very safe AFR | Tightened, still soots a stock DPF acceptably |
| EGR | Full strategy | Usually left on for a road file |
On SID803 / SID206 the tuner is moving torque limiters, requested fuel, rail pressure, VGT duty, smoke limiter and sometimes EGR strategy. It is not a magic 'plus 40 horsepower' switch. A good file is a smooth torque curve that the clutch and the DPF can live with.
Ford rated this engine 100 kW at the crank. A Sydney hub dyno of a healthy stock car showed about 79 kW at the wheels. After a DPF-in remap: 98 kW at the wheels, 371 Nm at the engine. When a UK site says 180 PS, they are talking flywheel. Both can be true.
Stage 1, stock hardware, DPF in, clutch checked. That is the map this engine was waiting for. Stage 2 if you already need an intercooler. Stage 3 only if you like invoices.
