Citroen C4 Stage 1: 115 hp → 146 hp

Factory output for the Citroen C4 1.6 Ehdi is 115 hp and 270 Nm. A Stage 1 remap targets 146 hp and 336 Nm — 31 hp (+27%) and 66 Nm (+24%).

Those are the figures we work to on this engine. They are a starting point, not a promise: the number we hand back is the one your car makes on our dyno, measured before and after on the same day, in the same conditions.

Where the 66 Nm shows up

On a diesel the useful change is torque, not peak power. Going from 270 Nm to 336 Nm fills in the mid-range, which is where a Citroen C4 actually spends its time — pulling from 1,800 to 3,000 rpm in a high gear, overtaking without dropping two gears, towing or carrying weight without the engine falling on its face.

Peak power moves too, 115 hp to 146 hp, but you will feel the 66 Nm far more often than the 31 hp.

What Stage 1 involves on a Citroen C4

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 115 hp baseline — a tired or faulty engine gets diagnosed before it gets mapped, not after.

The calibration is written for your car, not pulled from a file library. We adjust fuelling, ignition timing, injection timing and boost, then re-run the dyno to verify the 146 hp and 336 Nm figure and check knock, lambda and temperatures under load.

Turnaround is same-day for most cars. Stock file is archived, so the car can go back to standard whenever you want.

Which Citroen C4 this covers

These figures are for the 1.6 Ehdi as fitted 2010–2014. Engine code and ECU type decide what is possible, so send us the registration or VIN and we will confirm the exact variant before you book anything.
