im getting no responce in the focus section so ill ask you helpfull lot here!

right back from my holiday with a little cash to spare, i have been greatly considering getting bluefin for my focus tdci. but i want to ask a few questions.

what exatly does it do to the ecu?

has anyone expierienced any problems with the kit leading to major faults with the cars running?

will power increase be vastly noticeable or is it £500 down the drain?

and the cheapest place to find the bluefin kit??

regards

rob.
