McLaren's twin-turbo V8 engines — 3.8 and 4.0-litre — are masterpieces of engineering but still contain ECU calibration margins accessible via professional remapping. McLaren tuning is highly specialized and reserved for owners seeking maximum track performance.
The McLaren 720S and 650S with the 4.0T twin-turbo V8 respond to ECU optimization with sharper boost delivery and improved response at mid-range RPMs. Stage 1 can push the 720S significantly beyond its already impressive 720 PS output.
