How does the 1.3 CDTi respond?
It is a small-displacement engine, so the relative gain in flexibility is noticeable, particularly when overtaking or with the car loaded.
How does this differ from the Corsa C and D entries?
Each covers a different generation of the model. It is worth checking the one matching your car's year.
Is a remap worthwhile on a car of this age?
It depends on engine condition. On a well-maintained example it responds well, but remapping does not compensate for wear.
