I do 100% town driving and avg around 32-33 if i'm lucky. I managed to get close to 35mpg with a mix of motorway and town. I don't think the remap improved the economy or worsend it. DPF delete is on the cards should see a 5mpg improvement.
Danny, yours is a manual right? If so I'd expect it to be better but by 10mpg+ thats a pretty big difference!
How do you find the hidden ODO temp gauge? Might be worth checking my 'stat temps too!
