How does this differ from the main Astra entry?
This covers the J generation specifically. Our history records the model under several designations, so check both.
How much does the 1.4 Turbo take?
It is a small turbocharged petrol that gains noticeably in flexibility, which is what a car of this size needs most.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
