I bought a Skoda Octavia Vrs 2005 model a few months ago and got it tuned Stage 1. The car has been moving well, but the problem is the mileage. It gives only 5 KMPL in the city when driven with a light foot and a 7kmpl on the high way. The mileage was about the same when the car was stock. The cars have been reviewed, the injectors have been cleaned, the fuel pump has been checked and all sensors have also checked that, but the problem remains. Guys point me right direction.
