Less back pressure would make the turbo spool faster in all situations so everything from a traffic light GP to kick down on the motorway will feel a little quicker, probably have gained a couple of bhp and a little more torque too
So a possibility of a fractional improvement in my fuel consumption.
Seems dire at the moment. 24.5mpg on last tankful. But it was all very short journeys around South London.
Saying that, the official urban figure is only 25.2mpg for the auto.
