Stage 1 Eco remap figures
Stage 1 Eco is performance with economy in mind. It keeps most of the Stage 1 gain, so the car still pulls well, but the map is shaped for efficient, relaxed driving rather than flat-out output. It is above the standard figures. We don't quote mpg, because economy depends on the car and how it is driven.

How Stage 1 Eco compares with Stage 1
Full Stage 1 on this Audi A8 is expected to give 387bhp and 515Nm (+82bhp, +74Nm). The Stage 1 Eco keeps about 76% of that power gain and 92% of the torque gain, so you get 367bhp and 509Nm: 20bhp less and 6Nm less than Stage 1, with the map shaped for efficient, relaxed driving, so it suits you if you want the pull and care about running costs. Both sit above the standard 305bhp and 441Nm.
What this means for your A8
Turbocharged petrol engines respond well to calibration changes: boost and timing are the main levers, and the result is a flatter, stronger torque curve as well as a higher peak.
Engine management is by a Continental SIMOS 8.4/8.5 unit. We read the ECU on your car and compare it with the software listed here before any work starts, so you know what to expect before you commit.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.
