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.

Who is the Stage 1 Eco map for?
- Drivers who want the pull of a remap for overtaking, motorways and towing, with the engine tuned with economy in mind.
- High-mileage drivers who want better performance and a more efficient everyday car in one map.
- Anyone who would otherwise take full Stage 1 but cares what each tank costs.
How Stage 1 Eco compares with Stage 1
Full Stage 1 on this Alfa Romeo 159 is expected to give 220bhp and 482Nm (+80bhp, +132Nm). The Stage 1 Eco keeps about 75% of that power gain and 92% of the torque gain, so you get 200bhp and 471Nm: 20bhp less and 11Nm 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 140bhp and 350Nm.
What this means for your 159
Diesel remaps work mainly on boost pressure, fuel delivery and torque limiters, which is why the Nm gain is usually the figure you feel in everyday driving, particularly when overtaking or towing.
This car is listed with a Bosch EDC16C39 engine control 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.
