Only experience I have with them is one from eBay - que the flaming lol - the father bought one for his 04 TDCi Focus called 'The Italian Box' which genuinely gave him increased torque and fuel economy as it said on the tin! It plugged in betweem the MAF and wiring loom. I'm in no way able to guarantee it or any eBay tuninh boxes, but it does do what it says on the tin!
