Alfa Romeo Giulietta 2010-2014 1.75 TBi 235bhp 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 290bhp and 385Nm (+55bhp, +45Nm). The Stage 1 Eco keeps about 75% of that power gain and 91% of the torque gain, so you get 276bhp and 381Nm: 14bhp 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 235bhp and 340Nm.

What this means for your Giulietta

Without a turbocharger the improvement comes from ignition, fuelling and throttle mapping rather than boost, so expect a smaller but still noticeable change in response.

Engine management is by a Bosch MED17.3.1 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.
