I've got the same situation with my 1993. It's confusin

1993. 125,000 miles.
I can't go above 2000 rpm's and the boost won't go above middle yellow.
I'm not sure if the discussion about the Bypass Control Valve applies to the control valves that 1993's have on the left hand side above the wheel well that has 3 nipples and one electrical connection. I believe I can check my control valve by seeing if it has 30 ohms when hot.
I am also hypothesizing that I may have fuel delivery issues and am changing the fuel filter and looking for constrictions in my fuel line, which I has a splice in it of fuel pipe because I couldn't get the plastic fuel line back on the check valve of the fuel pump. The fuel line has been just stuck into a piece of gas hose with a clamp on it and I have been warned that it's not a good permanent fix.
I've changed the vacuum lines this week and the spark plugs are nearly new, having been replaced at 120,000 miles several months ago. I'll also replace the fuel filter.
In my case, I also have intermittent limp home mode.
My biggest problem is trying to separate out of the BB only the information on boost shudder that applies to my 1993.
In any event, by the time I am through doing everything, the fuel and air delivery system will be well maintained. I think that to avoid these headaches a 9000 fuel and air system has to be meticulously maintained.
