The poor economy on motorways has always been a factor for me. Maybe i just need to remove some lead from my right shoe

Im off up to the highlands tomorrow so I'll see what can be achieved. As for the panel filter I was sceptical about it but the ITG has been manufactured to a very high quality, the car feels much happier in 5th and 6th at low engine speeds. I also used to get a very uneven idle on cold morning with a horrible occurence whereby the engine revs would drop away when I accelerated after id changed up a gear for the first few minutes in the morning, it felt like the car was braking. That went as soon as the filter was installed. Although I also blocked the holes in the resonator which increased air flow to the engine

Rochie thats interesting what you say about the cruise, I was under the inpression that it increased economy?
