Stage 2 Remap

Maximum Performance with Supporting Hardware

For drivers who want to take their vehicle’s performance to the next level, a Stage 2 remap from RAT Remaps & Tuning is the next step beyond standard ECU tuning. Unlike Stage 1, which works within the limits of factory hardware, Stage 2 tuning is designed for vehicles fitted with performance upgrades such as a high-flow downpipe or de-cat, performance intake system, and upgraded intercooler. With these supporting modifications, the ECU can safely unlock significantly higher power and torque levels.

What Is a Stage 2 Remap?

A Stage 2 remap is an advanced calibration of your vehicle’s ECU that takes advantage of improved airflow, cooling, and exhaust efficiency provided by aftermarket components. It allows the engine to run more aggressive boost pressures, richer fueling, and more advanced ignition timing all while maintaining safe operating conditions.

Because the engine is no longer limited by restrictive factory components, it can achieve far greater output and sustain that power for longer periods, especially under hard acceleration or track use.

Benefits of Stage 2 Tuning

Substantial horsepower and torque increases often 30–50% above stock.

Improved turbocharger efficiency with stronger boost response.

Enhanced throttle response and mid-range acceleration.

Smoother power delivery with extended powerband.

Ideal for track, performance driving, or spirited road use.

Hardware Requirements

Stage 2 tuning requires certain supporting hardware to achieve safe and reliable performance. These may include:

  • High-flow de-cat or sports catalytic converter.
  • Performance air intake system.
  • Upgraded intercooler for improved charge-air cooling.
  • Optional: performance exhaust system, uprated clutch (for manual cars), or upgraded fuel pump.

Our team can advise on the best hardware setup for your specific vehicle before remapping begins.

How the Process Works

  1. Pre-tuning diagnostics and inspection to ensure the vehicle is healthy.
  2. Hardware verification to confirm that all supporting mods are in place.
  3. Custom ECU calibration using professional software to maximise performance.
  4. Testing and fine-tuning to ensure reliability, smooth drivability, and maximum output.
