My focus is a 1.6 tdci. So you'd recommend a bluefin? Thanks for the info :-) what car do you have?

its more or less the same thing, they are pre written maps, the difference with bluefin is , you dont need a dealer to come round your house with a laptop and re-programe the ecu, you get the device to do it yourself, also with bluefin you can set it back to factory settings at no extra cost, a dealer would need to come back out to do the same thing and charge you for it.
i had mine done via a dealer (celtic tuning)
