I've had a good Google for tuning the engines in the current Fiesta and Mondeo models. Because they're so new, there's little information. Anyone know of somewhere that has got some good results, and what I should expect for my money? The Fiesta has 68bhp as standard. Looking at the chip for the BMW 330d, it gets almost 100bhp/litre when chipped. Applying that sort of specific power output, almost 140bhp would be quite nice in a Fiesta ;-)
