Its been a while...... but I need some help please.............
My S3 has a problem with intermittent boost. It will either not boost at all or massivley overboost to 25lb !!!!. Ocasionally it will boost normally. I also notice that the wastegate seems to chatter different amounts randomly (either a very small amount or fairly audible). The ambient temprature seems to make no difference. Has anyone else had this problem? Any help would be appreciated.
