I've got the one no one talks about anymore, Kenne Bell 2.8LC kit. Makes 602/525 on an insanely conservative tune. Idles and drives like a stocker. I've daily driven it like this since for nearly a year now (installed in December of 2012) and have no ill effects at all. And I am not known for being easy on her, LOL! Engine and trans (M6) are all still bone stock.
