What is the 0.9 TwinAir?
It is a two-cylinder turbocharged petrol with a very distinctive character. Being turbocharged, it offers a worthwhile margin despite its size.
Is a remap worthwhile on a small car?
Yes, precisely because the starting figures are modest and the car is light. The relative gain is very noticeable in everyday driving.
Do you do pop and bang?
Yes, with 10 files it is among the more requested on this model. Note it can affect exhaust components and is not intended for road use.
