Is it worth chipping my Ford Focus for economy?

I've a 2010 Ford Focus 1.6 TDCi. Will remapping the engine's ECU really improve the economy? I'm getting 46- to 49mpg now and there are 57k miles on the clock (it's a UK import).

Hi Denis,

Chipping an engine can be beneficial but to be honest I don't think it's really going to help you here. If you're already getting nearly 50mpg on average then you're doing pretty well as it is. Chipping might boost that a bit but you're into unknown territory then with engine longevity, you might drive up your insurance and you might find a chipped car hard to sell on again.
