laptop tuning?
 

Hi, My Dad has a 2007 GTI and he would like to unlock its full potential. He was asking me (I'm a 6th year general auto tech) if i could do this with a laptop. If I thought i could he would buy me the laptop and whatever software was needed. So here I am, trying to find out what I can about doing this. This is and area of the trade I wouyld really like to get into. any info would be helpful, i would be happy to try to answer any tech ?'s anyone may have, although my vw experience is limited to mostly older models.
