Suzuki Grand Vitara 2005> 1.9 DDiS 127bhp remap figures
Thinking of remapping a Suzuki Grand Vitara 1.9 DDiS 127bhp? The standard car makes 127bhp and 300Nm; with a Stage 1 remap from our Leicester workshop we expect around 177bhp and 398Nm, up to +50bhp and +98Nm.

Stage 1 remap figures
A Stage 1 remap is a software-only change to the ECU on an otherwise standard car. It needs no extra parts, which makes it the usual starting point.

Who is the Stage 1 map for?
- Drivers who want stronger pulling power for overtaking, hills and towing, with no parts to fit.
- Daily and motorway drivers who want the engine to feel less strained at cruising speed.
- Anyone who wants the biggest software-only change we list for this engine.
What this means for your Grand Vitara
On a diesel the biggest change is normally torque: the remap changes how much fuel and boost the ECU allows across the rev range, so pulling power arrives earlier and holds on longer.
Engine management is by a Bosch EDC16C0/C3 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.

Stage 1 questions
How much power does the Stage 1 map give the Suzuki Grand Vitara 1.9 DDiS 127bhp?
We expect 177bhp and 398Nm against 127bhp and 300Nm as standard: up to +50bhp and +98Nm. These are expected figures, and we confirm what is achievable on your own car after a diagnostic check.
Does a Stage 1 remap need any extra parts on the Suzuki Grand Vitara 1.9 DDiS 127bhp?
No. Stage 1 is a software-only change to the ECU on an otherwise standard car.
Is there a gentler map than Stage 1 for this engine?
Yes, two. Stage 1 Eco is performance with economy in mind: 165bhp and 390Nm expected. The Eco map is economy first: 161bhp and 385Nm. Both still sit above the standard 127bhp and 300Nm.
Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
