Volkswagen Golf (MK4 1J) 2001-2004 2.0 GTi 115bhp Stage 1 Eco remap figures

Who is the Stage 1 Eco map for?

• Drivers who want a quicker, more responsive car, tuned with economy in mind.
• Daily drivers who want strong mid-range pull without giving up efficiency.
• 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 Volkswagen Golf is expected to give 130bhp and 187Nm (+15bhp, +15Nm). The Stage 1 Eco keeps about 73% of that power gain and 93% of the torque gain, so you get 126bhp and 186Nm: 4bhp less and 1Nm 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 115bhp and 172Nm.

What this means for your Golf

On a turbocharged petrol engine a remap adjusts boost, ignition timing and fuelling together, so both power and mid-range torque rise and the car pulls harder out of corners and junctions.

Engine management is by a Bosch ME7.5 unit. Older engine management is simpler to work with, but age matters: worn sensors, leaks and tired components can hold back what a remap delivers, which is why we run a diagnostic check first.

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.
