#6978, "RE: Hesitation under moderate to hard boost" In response to In response to 0
Welcome to 2GNT, man. We're a mostly non-turbo car site, but we do have a forum for the turbo engine. There's some really good people lurking in there, so I'll move this over there where they will see it.
On a 2GNT, I'd suspect plugs or wires right off the bat, but it could be something else. I don't know too much about the 4G63... yet.
