Hi there,

Im new to the forum and Ive recently just purchased a 2016 diesel Focus ST3 and was looking into giving it some performance upgrades. Just wanted some opinions of whether doing the Bluefin or a tuning box like the one Ive posted in the link below would be the best option. Looking at the websites the tuning box gives marginally better performance gains and are both a similar price.

Tuning Box

Bluefin

Thanks,

I have had both tdi tuning box on a mk 2 focus and my st mondeo I did 70.000 miles with the box on the focus l now have a mk3 2.0 tdci 140 zetec with a bluefin witch has 50.000 miles with no problem
The car is standard apart from the bluefin on a rolling road it made 178 bhp and 275 foot pound toque witch is what bluefin say it will make a proper map will always be better as you get a smoother power delivery and I. Used to take the bluefin off if it went in for service only take 15 minutes.
