hey everyone

well iv been looking for a good vw audi forum for ages but this seems to be one of the best, well basicly i have got a new company car ^above and well its just abit slow in lower gears iv spoke to a couple of people and found that due to its age a tuning box is reconmended due to warrenty issues.

i was just wondering which are good one to go for and if its worth buying second hand , can they deffo not be traced via audi when it goes in for servising , thanks
