Turbo Boost

[Dave & Michelle Anseeuw <Anseeuw@Prairie.ca>]

Hi
I'am overhauling my 86  QT and when done I would like to increase the
boost. I've been reading up on doing this which brings me to question.
On my engine factory boost is around  1.3 bar (18psi) but on Scott M.
web site it say not to pressure test the ECU above 15psi  or the
pressure sensor could be demanged. I don't understand the factory boost
is already above 15psi.
Could someone shed some light on this for me.

Thanks Dave Anseeuw
