The chips that you are talkin about for the VW's are the turbo VW's the chip "ups" the boost level from what i understand so thats why the VW's are gaining so much power. As far as for our cars the only chips I've seen have been off ebay and i think all those do is mess with you A/F ratio and rev limiter(?). I think some1 actuall dynoed one from this site and lost 2 hp. not sure who it was tho. Correct me if im wrong guys....
