Firstly RedUn can I say that I am extremely jealous. Have just been away in Wales and was gonna get mine done at Superchips franchise in Wrexham but the 500 notes put me off in the end. Think I might have to sort it out when I'm away next though. So a few questions

How long does it take, and did you get a rolling road set up? If not how did you get the performance improvement figures?
PS. d.griffiths, the superchips website is
www.superchips.co.uk which has an outlet finder on it, I'm fairly sure there will be one in South Wales, and it also has the power curves and other stuff on.
