Boost Goes Away

I am having a strange issue. Last night, a few minutes after
accelerating hard (full boost) onto the highway, I noticed that my car
was no longer producing anywhere near full boost. Since it was dark, I
decided I would take a look at it today, after work. But this morning,
all was well again; plenty of boost. Good boost on the way home from
work in the afternoon, until I again accelerated hard through gears,
then the boost fell off again. I stopped home, changed clothes, and
jumped back in the car: full boost! Anyone have any ideas?
At rest, key on, engine off, the boost gauge reads .8 bar. "Full" boost
is 1.6 bar, usually. I am running the IA stage III chip and have
struggled through a few issues since chipping back a couple of months
ago (not chip related). I have replaced the OXS, the intake temp sensor,
plugs, and wires; I also treated the MAF and TPS with Stabilant 22a.
How do my boost numbers sound? In the ballpark, or am I low? Thanks.
