Mclaren 600lt/570s/570gt/540c Stage 2 Tuning Package - Narkos performance

What the Stage 2 Package Includes

According to Narkos Performance’s literature:

• A hardware upgrade (at minimum the downpipes with integrated heat-shield) plus

• A custom ECU tune / remap tailored to the car after installation of the hardware.

• Specifically, for a 570GT example they list: stock ~560 HP → tuned ~732 HP / 930 Nm torque. 

• They emphasise: “A stage 2 remap involves recalibrating the ECU software, combined with necessary hardware upgrades

• Benefits such as:

  • Up to +40% power & torque (depending on hardware) Narkos Performance

  • Enhanced throttle response, improved sound, deeper exhaust note, calibrated crackles/flames (optional) 

• The downpipes they install are described as “aircraft-grade SS304 stainless steel, TIG welded … integrated thermal heatshield

What It Means Practically for McLaren 600LT / 570S / 570GT / 540C

If you apply this package to the models you listed, you can expect (subject to existing condition, supporting hardware and tuning scope) something along the lines of:

• Removal or upgrade of factory downpipes (less restriction → better turbo response, lower back-pressure)

• ECU/engine remap that raises boost (if turbocharged car), advances ignition/trim, improves air/fuel etc

• Sound upgrades: deeper tone, crackles / flames (if exhaust/hardware supports)

• Improved throttle response, stronger mid-range & top-end pull

• Possibly changes in cooling, heat management (thanks to the heatshielded downpipes)

• Note: The magnitude of power gain depends on the car’s stock condition, previous mods, fuel quality, cooling, and how aggressive the tune is. For the 570GT they achieved ~+172 HP / ~+370 Nm. (560 → 732 HP, torque 930 Nm) 

Specific for Your Models

• For the McLaren 600LT and 570S/570GT/540C (which share the M838T engine in various states) the Stage 2 hardware + tune should deliver substantial uplift over stock.
  

• We Make sure the tune is tailored to your exact variant
