I don't know about the whine - but the stumble I have on the 89 760 I just bought. It too has the Garrett.

You might try to check the small red check valve (in the vac line) between the BOV (by the #1 cylinder) and the intake manifold. It is supposed to have resistence when you blow through it both ways according to the FAQ's. I have a new one on the way as mine was showing bad.

One of the comments in the FAQ's said that this fixed the stumble prob.

Another thing that I am going to check ASAP is the RSR (radio suppression relay). Check this link.

Be blessed in your quest!
