How does this differ from the other Astra entries?
This covers the G generation specifically. Our history records the model under several designations, so it is worth checking all of them.
Do you cover the 2.0 Turbo petrol?
Yes, it is present in our catalogue and accounts for part of the Stage 2 and Stage 3 work on this generation.
Is a remap worthwhile on a car of this age?
It depends on engine condition. A well-maintained unit responds well, but remapping does not compensate for wear.
