Iv just come off the phone to rising sun performance, they said they charge about 2 hours on the rolling road wich is about £150 - £200 to set up these 2 items but you know the safc wont control everything and you wont be getting the full potential out of your car, it is a cheep way of semi mapping it though! However, iv just noticed your in scotland and they are in alton near winchester, but atleast its a guide line for you!
