How are you controlling your boost? bleed valve? etc
if so, it is perfectly normal too see a short spike then drop and hold boost, but that does seem like quite a drop in boost

i control the boost with the actuator
i also thouth its a big drop in boost
it runs fine so i don't think its an air leak
could it be the pipe's collapsing?? or insn't the boost high enough for that??

the spring in the actuator might be to soft or is worn out
