Have you done any logs when driving to see if it's making requested boost etc?

No the solenoid wasn't changed. I never got any boost errors which is why I didn't change them. Would they cause a major low down power issue?

I only have a bmw c110 code reader which doesn't show me boost (unless i'm missing something?). Might have to get one of them boost testers.
