Self-confidence is an essential part of humanity.  A person with self-confidence generally likes themselves, is willing to take risks to achieve their personal and professional goals, and thinks positively about the future.  Someone who lacks self-confidence, however, is less likely to feel that they can achieve their goals, and tends to have a negative perspective about themselves and what they hope to gain in life.  The good news is that self-confidence is something you can improve! Building self-confidence requires you to cultivate a positive attitude about yourself and your social interactions, while also learning to deal with any negative emotions that arise and practicing greater self-care. You should learn to set goals and take risks, as well, since meeting challenges can further improve your self-confidence.
You may want to pick up a cheap vacuum test kit to see if there is sufficient vacuum at the turbo. Check all pipes for leaks.
The solenoids will only get voltage when the ECU wants a vacuum (or not, don’t know which way it goes).
On startup, my EGR vacuum was “sucked” then eased off after a few seconds (10-20)
On startup/idle, my turbo vacuum was sucked and stayed sucking till the van wanted to change its position.
So, on my van, after say 20 seconds, as EGR vacuum request is “off” and Turbo vacuum request was “on”, I’d expect different voltages at the solenoid as they are doing opposite things. Its all from the ECU. Easier to test with vacuum kit.
