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 as required. 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.
