Audi S6 (2012 – 2018)

TTFS Stage 2 ECU Calibration – Audi S6 (4.0T)
More boost. More torque. More excitement from Audi’s twin-turbo V8.

The 2014 Audi S6 rolls off the line with a strong 410 awhp, but the factory calibration leaves significant power and response untapped. TTFS Stage 2 unleashes the full potential of the 4.0T by optimizing boost targets, ignition strategy, torque management, and fueling—specifically for vehicles equipped with supporting hardware such as downpipes, upgraded cooling, or exhaust systems.

The result? A dramatic jump to 486 awhp, delivering a +76 awhp gain and noticeably stronger acceleration throughout the entire RPM range.

Key Benefits

• 410 → 486 awhp (+76 awhp gain)

• Stronger, more immediate mid-range punch

• Sharper throttle response & improved torque delivery

• Optimized boost control for harder, cleaner pulls

• Smoother top-end power and reduced heat-soak effects

• Retains OEM drivability, safety strategies & daily reliability

Perfect for S6 owners running bolt-ons who want maximum performance without compromising comfort or long-term dependability. TTFS Stage 2 turns the C7 S6 into a sharper, harder-charging powerhouse—ready for the street or highway pull.
