Suzuki Grand Vitara Stage 1: 109 hp → 146 hp
Factory output for the Suzuki Grand Vitara XL 7 20Hdi is 109 hp and 270 Nm. A Stage 1 remap targets 146 hp and 346 Nm — 37 hp (+34%) and 76 Nm (+28%).
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 76 Nm shows up
On a diesel the useful change is torque, not peak power. Going from 270 Nm to 346 Nm fills in the mid-range, which is where a Suzuki Grand Vitara 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, 109 hp to 146 hp, but you will feel the 76 Nm far more often than the 37 hp.
What Stage 1 involves on a Suzuki Grand Vitara
We read the ECU, log the car as it stands, and put it on the dyno to confirm the 109 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 346 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.
