at the beginning of march on holida in cornwall the turbo pipe went on my mondeo. after driving around 400 miles home with lost of exhaust smoke I got a new pipe fitted. since then however I feel like my car has aroung 10% less power. Is this just me the driver settling into the car (purchased middle of february) or could it be something else? could it be that the system is clogged from 400mile turbo-less drive home or any thing else?
