Finally set the timing and it didn't help the problem. Used to get 16.5 lbs. of boost, but now it starts stuttering at about 10 lbs.. Checked all the hoses, connections, etc. and found no problems. It doesn't really do it if I get the revs up to about 5500, it will take the boost ok then.
Any ideas from the all knowers?
