You'd have high boost lag if your turbo was running full boost. You'd have high acceleration if your BOV was stuck closed.

What about the other way around to the original posting. No turbo boosting or very little according to the gauge and hearing a whining pitch sound when you should be getting boost from the turbo?
Would it be a bad turbo unit, wastegate or BOV? This just started happening to me and not sure what to tackle or look for to confirm what is wrong. 87 turbo manual trans rob87 |

It would probably be cleaner for you to start a new thread. It's kind of hard to diagnose a "whine" without actually being there. I'd starts with checking the least expensive to replace components first: check IC plumbing for boost leak, check BOV for leak, test wastegate actuator movement with a bicycle tire pump.
Otherwise, yes, it could also be the infamous "whine of death" of the turbo.
