Just noticed this post or I would have answered earlier .The only one talking s*** is you if you say there is no chip for 2007 Fiesta 1.25 engine . Why so abusive to fellow poster trying to help / advise ???? If you go to Evolution chips or Bluefin you will see I am correct .Of course there wont be a massive increase in power with that engine but he can add to it by changing air filters , exhaust , cams etc. etc . especially as he states he does not want to change engine. It is not something that I can be bothered getting involved with now and pass on to a specialist performance tuning garage nearby when asked . They can and have got a lot more power by fitting new chip and remapping on that car but obviously nothing compared to what they can get on bigger engines/ turbo diesels etc.Naturally you dont want to go crazy and take it too far on such a small engine , knackering it in a few weeks or days .
