I removed both front and rear baffles plus fitted the G56 air filter housing, MPG went from roughly 30 to 35mpg.
Since then I have had the 569 cams fitted and the eco tuned at Krazyhorse.
At a steady 60-65 on the motorway I have seen 40mpg on a long run and spirited driving on A & B roads 30-35mpg.
When new it would do 27-30.
Even on a track day at Croft I got more than 20mpg.
I once brimmed it and ran it out of fuel just to see how far it would go on a tank and got 297 miles so I now fill up between 200-250 just to be on the safe side.
