Racechip who has tuned his Volvo with it

Hello all, I have a Volvo V50 T5 AWD Bj 2006. Recently I became aware of the company Racechip by a flyer. http://www.racechip.de/…/index.php?tplvar=a Well, I would be very excited to get some more horsepower out of the engine with so little effort. Does anyone have experience with Racechip here? Or do you have better suggestions/bzg tuning? Or is it a good idea to do a car with 100000Km on the tacho?
