I got my car back today as my brother said (NISR227).....
I spoke to Simon face to face and asked him about the unichip.....
His respone was what chris said, they don't do the UNICHIP anymore, the 2 ECU's they do for the GTiR are the Power FC and the Motec.
The Power FC does exactly what the unichip does, but a lot better and also does a lot more.
So I've decide I'm gonna go for the Power FC once my car has been run in. I'm aiming for around 360-370 BHP.
I've heard good stories about the Unichip, and I'm not knocking it, but my car is going back to ND in 1500 miles time so I might as well go for the Power FC.
