Stage 2 hardware, peace of mind and process

Stage 2 requirements

Stage 2 ready with the Custom Sport Filter Kit

At Stage 2, the engine's breathing is freed up with hardware, and the software is written to match that hardware. The target for this engine is 180 HP / 410 Nm.

  • Air intakeThe made-to-measure Legend Custom Sport Filter Kit or an intake suited to the car.
  • Intercooler & boostA vehicle-specific intercooler / blow-off valve to keep temperatures stable under sustained load.
  • Silicone boost hosesHoses and pipes that withstand the higher pressure.
  • Health checkIgnition, fuel system and clutch checked for this power level; the job takes ~4–8 hours (depending on parts fitted).

Included every time

Power with peace of mind

  • Original software backup — the factory software is read and archived before the job.
  • Reversal — the car can be returned to its original software whenever you ask.
  • Datalog check — boost pressure, ignition and air/fuel ratio are recorded and checked on a road test.
  • Vehicle-specific calibration — not an off-the-shelf file; tuned to the engine, hardware and fuel quality.
  • Pre-tune diagnostics — fault memory is read and engine health is checked before the software.
