Overview
Experience industry-leading B8 S5 V8 tuning from Jackal Motorsports — a complete transformation of your driving experience. This tune unlocks up to 30whp and 50ft-lb of torque gains over stock, unleashing the power Audi left behind from the factory. Features include Launch Control, Burble/2-Step options via cruise control stalk, improved fuel efficiency during relaxed driving, and Jackal ZF6HP TCU tuning for faster shifting and overall drivability improvements. Flash your tune right at home using the Jackal flashing cable — switch between tunes, octanes, or return to stock anytime, for free. The tuning suite flashes both your ECU and TCU.
If you have a supercharged S5, Jackal Motorsports holds the record for tuning the fastest 1/4 mile JHM supercharged B8 S5 V8 — an 11.26 @ 126mph, achieved with a full-weight, stock motor manual car equipped with the JHM Stage 2 inter-cooled SC kit, a 3.8″ pulley, 93 octane, and WMI. Even faster times are expected with better tire and launch setups. Already tuned elsewhere? Jackal offers a special switch-to-us discount — contact them directly for a discount code. From daily commutes to spirited drives and track days, this tune is optimized for performance, safety, and enjoyment — not just dyno numbers.
