Hey guys,
I have a stock 06 STi and in the past two weeks I have noticed my L/100km being lower than usual for my daily commute.
Usually I get around 12 - 12.5 but now get 10.5 - 11
I have an ECUDatascan so I had a look at where my boost holds with pedal to the floor in second and its at 13.5Psi
First things the come to mind is either the ECU is playing up or I have a boost leak?
Is there any other data I can look at on the ECUDatascan which can give me a better idea of whats going on?
Thanks!
