Sounds like the logic for the cruide control is exactly backwards. There is supposed to be a switch(somewhere under the dash) which tells the ASC that the cruise control is on and do not go above base boost. Then when the cruise is disconnected it releases that signal which will allow you to go above base. I'd be looking at that signal. I've seen it documented at several web sites. Just google around and you'll find it. -Fred
