Unless you want it live mapped, Mark could possibly fit and setup a Stu supplied chip. Not sure that Mark maps Cosworths on anything other than Autronic, but you'd have to ask him to be sure.

Stu can supply closed loop chips for several spec's as far as I know, so unless going very big bhp, you could get the chip/injectors off him, and someone local to set it up/install.

Edit: answers all above, I was too slow replying
