Stage 3 is serious territory — a bespoke, high-performance calibration for vehicles that already have substantial supporting hardware. It's not a bigger Stage 1; it's a different conversation, and it only works when the build underneath supports it.
Stage 3 assumes major hardware is already in place — think uprated or hybrid turbos, uprated injectors, intercooling, fuelling and clutch capable of handling the output. The map is then developed bespoke to that specific build. Without the hardware, a Stage 3 map is meaningless and unsafe.
Most road drivers do not need Stage 3 — Stage 1 or 2 covers the vast majority of goals. If you're genuinely building toward big numbers, we'll have a straight conversation about the hardware required, the cost, and whether it's the right path before any work begins.
Stage 3 work is developed and validated carefully through the Viezu network, with your original file backed up. This is custom calibration, quoted per build.
