Oh right, well its a Hillpower chip which I got for about 170 but I think its 150 for members. When I got the chip I didnt notice an immediate difference apart from the raised rev limit (7.5k) which is very usefull as I always used to hit the limiter. But when I tested the car down a local (private) road the car was doing 105-107 when before it was doing 100, the power delivery is very linear so you dont notice the increase much. Good value Id say.
