And I'll definitely check out CMS. Prestons isn't too far from me (I'm actually much closer to Livo than Parra)I never bought the car for 'economy' but I'd like it to be a little more economical. If not I'm still happy!! Link to comment Share on other sites More sharing options...

It might help but I've never heard of anyone stating the dump upgrade helped. I have heard of induction & tune upgrades 'aledgedly' giving anything up to a 20% economy improvement Link to comment Share on other sites More sharing options...
