Identify your Vauxhall engine before choosing a tune

The 2 listed model families above cover the records currently in our library, not every Vauxhall ever produced. Select the generation and factory output matching your car; a shared model badge does not guarantee the same engine, ECU or gearbox.

Stage 1 normally retains standard performance hardware; Stage 2 requires the parts specified for that engine. Some ECUs need unlocking or workshop access at our Slough workshop.

Vauxhall gearbox considerations

Gearbox suitability is confirmed per vehicle.

Available figures are estimates, not a dyno result for your vehicle. If your engine is missing, send the registration and configuration for assessment rather than applying another variant's numbers.

    Really fast service, I explained what I needed to solve my problem with the car and they got the parts in, did the work and all was done smoothly and efficiently. Nice workshop and friendly, polite staff.

    I wanted to leave a genuine review, I got my car remapped on the 5th June 2026. Making the appointment was very easy, I didn’t have to wait too long for an appointment and had the option for someone to come to my house if needed. The remap was done within an hour or so. My light did come back on a week after the remap was done, but I was able to clear it with no issues and last weekend I took a 4 hour round trip to the beach and the light did not come back on when usually it does after about 1hr into a drive. The point of my long review is I highly recommend this company and I am very happy with the service provided.
