I post this for future "searches".
It turns out that it was most likely bad spark plugs! I should have listened to earthbrown from the start. I did replace all of the vacuum lines 1st, and that improved things to about 90% better, but the boost would occasionally not make it to the red-yellow zone.
Finally I pulled the spark plugs and they were awefull, huge gap and rounded electrodes. Once I replaced the plugs (with NGKs)the boost always goes to and stays about 1 needle width into the red! Hurray!
