Hyundai H Series Stage 1: 163 hp → 197 hp

Factory output for the Hyundai H Series H300 25 CRDi is 163 hp and 392 Nm. A Stage 1 remap targets 197 hp and 456 Nm — 34 hp (+21%) and 64 Nm (+16%).

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.

What 34 hp changes on the road

A turbocharged petrol responds to a remap mostly through boost and ignition timing. Taking the H300 25 CRDi from 163 hp to 197 hp, with torque from 392 Nm to 456 Nm, sharpens throttle response and shortens the gap between asking for power and getting it — the car stops feeling like it is thinking about it first.

Gains of this size (+21%) are normal for this kind of engine on pump fuel, with no hardware changes.

What Stage 1 involves on a Hyundai H Series

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 163 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 and boost pressure, then re-run the dyno to verify the 197 hp and 456 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 Hyundai H Series this covers

These figures are for the H300 25 CRDi as fitted 2007 onwards. 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.
