no doubt.  my point is that the thermostat is
currently not working, and as a result, the car
gets up to temp only when idling in one place. 
as i drive it, it cools down.  so, my only window
of opportunity to check boost levels was the 15
seconds that i had after letting it idle.  

keep in mind that before i let it idle, i had
just returned from a 15 minute test drive which
was how i found out that the t-stat was finished.

funnily enough, i've been driving vdubs for the
past 10 years now, and the first thing that
someone taught me way back then is that until the
car reaches 80 degrees celsius, don't rev past
4000rpm. 

i guarantee you that while she's cold, she'll be
driven carefully.  once she's up to temp, tho,
she'll be getting all kinds of right foot lovin.

thanks for the reply. tho.
