Hi Dan, Thank you for your help regarding my Focus. I managed it in the end and rang John at Wincanton to thank him and explain. The Tunit is excellent; 65.5 mpg over 55 miles to Bristol at normal speeds and 63.5 mpg at normal speeds on the motorway to London the following day. Overall this is 8-10% better than before. Brilliant!

Stephen , Ford Focus 1.8 TDCi

Since fitting the tunit product I noticed smoother response from the engine even though the car was only 6 months old and obviously more power. Power difference showed more on the motorway when overtaking as plenty of power on tap without gear changes. Fuel consumption is good averaging just under 50mpg if i drive softly enough. Very pleased with the product.
