funniest thing, guy I know at the plant that owns an ATS got his tuned and it doesn't tremble anymore, and it hauls ass to boot!,
while I realize many of you aren't in these cars to modify them, and, an aftermarket tune is no excuse/proper solution.... my point is, it fixed his car, so its gotta be an issue thats fixed easily. I'm still willing to bet its an A/F ratio issue. But GM needs to seriously get on this.
but either way... once I get my intake and DP made I'm getting it tuned, things gonna fly
