The Ecotune Stage 3 software for the Polo GTI 1.8TSI is specifically engineered to maximize the efficiency of the IS20 turbocharger. This calibration provides a massive increase in torque and top-end power, effectively turning the Polo GTI into a lightweight powerhouse capable of 330hp+ on 99 RON fuel. Featuring Ecotune's advanced safety protocols, this software ensures peak performance without compromising engine longevity.

Categorized Hardware Requirements
To support Stage 3 power levels on the 1.8TSI platform, the following hardware categories must be addressed with premium components:
1. Turbo & Airflow
Utilizes the IS20 turbocharger (found on Golf GTI models). Requires high-flow induction from Forge, Racingline, or APR. Cooling must use do88 or APR intercoolers.
2. Exhaust & Downpipe
Large-bore downpipes are mandatory to reduce backpressure. We recommend high-flow solutions from Scorpion or Milltek.
3. Fuel System
Upgraded fueling is necessary for Stage 3 flow rates. Flex Fuel capabilities are available when paired with an ethanol sensor kit.

Installation Requirements: Your vehicle is booked for Ecotune Stage 3 tuning. Before any calibration work begins, a full pre-tune inspection must be carried out. This inspection is essential for Safety & Reliability, Correct Hardware Verification, Ensuring Accurate Calibration, and Preventing Avoidable Issues. We check: Turbocharger, Cold air intake system, Turbo inlet pipe, Low-pressure fuel pump (LPFP), High-pressure fuel pump (HPFP), Upgraded injectors, Intercooler, downpipe, exhaust components, and all performance-related modifications. All software must be reviewed and signed off by the Ecotune Calibration Team. The vehicle will not be released in a tuned state until this approval process is completed.
