McLaren 720S ECU Tuning – Stage 1 & Stage 2

Unlock the full potential of your McLaren 720S with Momentum Motorsports’ precision-engineered ECU tuning packages. Both stages deliver massive gains in horsepower, torque, throttle response, and overall driving experience—while maintaining reliability for the M840T twin-turbo V8 platform.

Stage 1 Tune

+110 HP / +120 TQ (Approx.)

Stage 1 provides a significant performance increase with no hardware modifications required. Ideal for owners looking for a dramatic boost in power while retaining full OEM components.

Features

• No hardware changes required

• Major gains across the entire RPM range

• Faster turbo spool & sharper throttle input

• Smooth, predictable OEM-like drivability

• Optimized boost, ignition, torque, and fuel mapping

• Top speed limiter removed

Stage 2 Tune

+150 HP / +145 TQ (Approx.)

Stage 2 is built for drivers who want the most aggressive power delivery the factory turbos can safely achieve. This calibration delivers stronger mid-range acceleration and harder top-end performance.

Requirements

• High-flow race downpipes (mandatory)

  • Reduced backpressure

  • Better thermal control

  • Enhanced turbo efficiency

Benefits

• Stronger mid-range and top-end power

• Higher boost targets

• Maximized airflow and torque curve

• Noticeably more explosive acceleration

Recommended Upgrade: Turbo Inlets

We highly recommend upgrading the OEM plastic turbo inlets, as they are restrictive and prone to collapsing under higher boost levels.

Upgraded Inlets Provide

• Increased airflow to the turbos

• Lower pressure drop

• Better boost consistency

• Improved reliability for Stage 1 & Stage 2

Optional Flame Feature (Stage 2 Only)

• Flames available upon request for Stage 2 clients

• Aggressive overrun tuning for visual flare

• For off-road / competition use only
