Can you remap Vauxhall CDTi engines?

Yes, CDTi diesel engines respond very well to remapping with typical gains of 25-35% more power and torque.

What about VXR models?

VXR models are among our most popular vehicles to tune. The Astra VXR and Corsa VXR deliver excellent gains with Stage 1 remapping.

Do you tune Vauxhall vans?

Absolutely. The Vivaro and Movano are popular for commercial tuning. Improved torque makes loaded driving much easier.

Our Services for Vauxhall

Vauxhall's CDTi diesel range — from the 1.6 in the Astra to the 2.0 biturbo in the Insignia — responds impressively to Stage 1 calibration. The popular 1.6 CDTi gains 25-30bhp with noticeably punchier mid-range torque, while the Astra VXR's 2.0 turbo petrol can see gains of 40-50bhp. Vivaro van drivers also benefit from improved pulling power for loaded driving.

For Vauxhall CDTi fleet and commercial operators, our economy calibrations deliver measurable fuel savings. Vivaro van drivers covering high mileage typically see 10-15% MPG improvements through optimised injection timing and boost management. The Insignia CDTi is also a strong performer for sales reps and commuters looking to reduce running costs.

Vauxhall CDTi models are among the most common vehicles we see with DPF and EGR problems. The Insignia 2.0 CDTi and Astra 1.6 CDTi are frequent offenders — particularly when used for short urban trips that prevent full DPF regeneration. We trace the specific fault code, assess sensor health, and apply targeted software solutions.

Newer Vauxhall models running PSA/Stellantis platforms (Mokka, Grandland, new Vivaro) use AdBlue SCR systems that can develop NOx sensor failures and injection crystallisation. The warning lights can be persistent and confusing — we diagnose the specific component fault and apply the correct software fix to restore normal operation.
