This is the same engine family as the focus tddi, this doesnt have the intercooler and the turbocharger compressor is smaller than that of the focus. 75bhp is what yours would produce, superchips have a bluefin for it. When I was planning on tuning my fiesta van I intended to get it running the same sort of power as the remapped tddi focus. According to superchips a remapped focus tddi will run 120bhp, I emailed a few places in the hope of having a custom map made up.

I got as far as one guy who wanted to check my ecu for compatibility for remapping as he was doubtful but I explained that superchips had a blue fin he was then confident he could work something. I also bought a focus tddi turbocharger but that was as far as I got, my plan was to fit a front mount intercooler, focus tddi inlet manifold blank the egr, fit the focus turbo and go for a larger bore exhaust system.

The mk5 fiesta didnt have the tddi for that long before the mk6 came in and from looking about next to nobody had gone to enough troubles to tune one.
