rs4 performance chip
I was reading recently about performance chips where all the chips out there were rated. The website that had it recommended the rs4 performance chip.
Is there anybody out there who has tried this chip and what kind of results did you get.
I just stumbled on the site the first time and I havent been able to find it again.
