Common questions.
Will Audi detect the RS6 tune?
Audi logs boost events on the C8 platform. Free stock-revert before any planned dealer visit.
Do I need downpipes for Stage 2?
Catless or high-flow cat downpipes are required for the 800+ wheel hp range. We map the supporting mods together.
Does the C7 RS6 use the same tune as the C8?
Different ECU calibrations entirely — same 4.0 TFSI but different mapping platforms. We tune each as its own platform.
How long does the RS6 appointment take?
Stage 1: 2–3 hours. Stage 2 with mods to install: full day.
