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