eratic boost in 2nd

I have been trying to solve boost problem on 2 97 9000 cse
this occurs in 2nd gear on 5 speed and 2nd/3rd on auto. the issue seems to be the same for both cars. I have had an 86 and 95 9000 that did not do this.
if you are crusing and whack the throttle the car may or may not get full boost. on the 5 speed if you only get base boost, it will after 2 seconds jump to full boost. sometimes it will jump to full boost immediately but then fall back to base boost then go back to full and hold.
the auto will do almost the same thing with 3/4 thottle where it will jump to full boost but then fall back to base boost unless more throttle is given.
I have changed all vaccuum hoses on both cars, I put 101 octane race gas in one to see if it could be some weird knocking issue
tried different wastgate actuators and even wastegates. bpc valve seems to be working, could it be a map sensor ?
