Cannot Rev past 4000 rmp !?!

[Robert Dupree <rdupree@sidley.com>]

I think I have a problem folks.  While driving to Michigan today I noticed that the '87 5kTQ was not building as much boost as normal.  After paying closer attention it seems that the car will not rev past 4000 rpm.  Boost is maxed at 1.0bar (on the crapolla dash guage) where the normal reading will get to 1.7bar.  Any ideas what to look for?  I feels like the car just looses all guts above 4000, below that things are relatively normal.

PS: we are having mail problems so if you would respond to both my addresses it would be helpful.  The
other one is dupreer1@pilot.msu.edu
