2G not holding boost...

[3134]

i have a 97 gst w/ s16 g and a turbo xs mbc. I recently turned up my boost from 9 psi which would hold in high rpm to 14 psi. I instantly drop to 13 psi and then will steadily go down to 10-11 psi (around 5500-6500 rpm). btw i have a 1g bov as well. So any suggestions why i am not holding boost?

first check for boost leaks, then you may want to check your fpr and your fuel pump, a few weeks back a friend was having the same problem it was his fpr was messed up causing for the boost to just drop like this

its weird, i checked for leaks and i dont have any, but im not losing boost like a drop, instead it is a steady drop at extremely high rpm. Sometimes it will be at redline. I just dont feel it should be dropping at all that is why i am concerned.

I'm having the same problem but mines with a 20g. I'm also using a turbo XS boost controler dose any one think that could be the problem?
