David ,Ford Mondeo TDCI ST

Took it off the Jag & put it on to a 2006 Mondeo TDCi ST, fitted with a K&N Induction kit, on a trip to Manchester at no more than 70 mph on cruise control it returned 62 mpg!!, this was with the A/C on & 3 x passengers in the car, the car is smoother, and the pick-up is just awsome, my tunit was the 1st one fitted to a Jaguar diesel in the UK, and was set up on the rolling road at Chorley by Neil Bromley, It would be nice to find out what the ST is puting out in BHP, very happy with the TUNIT & the back up both from Chorley & the local agent in Newcastle
