What the car needs
Required modifications: Stage 2, Diesel.
Hardware
- Sport / decat downpipe (or DPF removal where legally permitted off-road)
- High-flow air intake (recommended)
- Optional: catback exhaust for lower backpressure
Software / calibration
- DPF / EGR / AdBlue switched off in software (where lawful)
- Boost & rail pressure raised to match new airflow
- Smoke limiter relaxed in line with hardware
- Lambda + EGT safeties retuned
Stage 2 keeps the factory turbo and internals. Final figures vary slightly with the exact hardware fitted.

About this calibration file
The Stage 2 calibration for the 2005 Citroen Xsara 1.6L Turbo Diesel is written for vehicles with supporting bolt-ons: a higher-flow downpipe or sports catalyst, upgraded intercooler and upgraded intake are recommended. Boost targets, fuel-rail pressure, injector duration and VGT positioning are pushed further than a Stage 1 map while keeping exhaust-gas temperatures inside safe bands.
This file matches a Bosch ECU with hardware number 0281012468 and software version 374952. Verify both identifiers in your flashing tool before writing — an ID mismatch is the most common cause of a bricked ECU. If you are unsure, upload a read of your original file via the file-request wizard and our engineers will confirm compatibility before you flash.
Projected output on a healthy, stock-hardware example of this engine: 126 HP and 306 Nm at the crank — a gain of +37 HP (42%) and +98 Nm over the factory 89 HP / 208 Nm baseline. These numbers are sourced from our Vehicle Performance Database, which aggregates dyno results across this engine family. Real-world gains depend on fuel grade, ambient temperature, mechanical condition and intake/exhaust state.
The file is delivered as a ready-to-flash BIN (and ORI backup where applicable) compatible with all major tools — KESS V2/V3, KTAG, AutoTuner, CMDFlash, Dimsport New Genius, MPPS, Flex, BFlash, PCMFlash, MMFlash — via OBD, bench or boot-mode as supported by your ECU family. Checksums are pre-computed and verified; no additional checksum tool is required. All files include a free revision if post-flash logs reveal a fuelling, boost or EGT issue.
