About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 2005 VW Golf 2.0 TFSI GTI (147 kW, 200 hp), for its Bosch MED91 ECU with hardware 0261S02080, part number 1K0907115B and software 387484 (1037387484). Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on the 2.0 TFSi GTI raises the boost, sets the ignition and the fuelling to match and lifts the torque limits, within what the standard turbo and fuel pump hold. It wants the fuel octane the car was made for, or better.
The VW Golf 2.0 TFSI GTI carries the 2.0 TFSi GTI engine, 200 hp and 280 Nm from the factory. On this engine, Stage 1 usually gives about 240 hp and 360 Nm (+40 hp, +80 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For software 387484 of the VW Golf 2.0 TFSI GTI we sell the original and Stage 1, each made from the same original read. Every file downloads straight after payment.
The Bosch MED91 ECU in this car is read and written over OBD and on the bench, with tools such as Alientech KESS3, Alientech K-Tag, Autotuner, MagicMotorsport FLEX, CMD Flash and Dimsport New Genius. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
Catalyst off, DTC off, speed limiter (Vmax) off, pops and bangs and anti-lag can be added to this file on request, for off-road and competition use: send us your read through our file service and our engineers add them (any file £50, from £30 in packs).
Hardware 0261S02080 is the number on the Bosch ECU's label. Software 387484 (1037387484) is the calibration inside it: a read with hardware 0261S02080 and another software number needs a different file. Part number 1K0907115B is the car maker's number for this ECU.

Yes, on request, for off-road and competition use: catalyst off, DTC off, speed limiter (Vmax) off, pops and bangs and anti-lag. Upload a read through our file service and an engineer builds it (any file £50, from £30 in packs). The buyer is responsible for using it where the law allows.
