Alfa Romeo Giulietta 2010> 1.4 TB MultiAir 170bhp Stage 1 Eco remap figures

Who is the Stage 1 Eco map for?

• Naturally aspirated owners who want a little more response and a more efficient, relaxed drive. Every map we list stays above standard.
• Drivers who want the small gain on offer without chasing peak output.
• Anyone who would otherwise take the full Stage 1 map but wants it tuned with economy in mind.

How Stage 1 Eco compares with Stage 1

Full Stage 1 on this Alfa Romeo Giulietta is expected to give 205bhp and 303Nm (+35bhp, +53Nm). The Stage 1 Eco keeps about 74% of that power gain and 92% of the torque gain, so you get 196bhp and 299Nm: 9bhp less and 4Nm 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 170bhp and 250Nm.

What this means for your Giulietta

Naturally aspirated petrol engines have no boost to raise, so gains from software alone are more modest than on a turbocharged car and come from fuelling, ignition and throttle response.

Engine management is by a Marelli 8GM 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.
