I was enjoying a drive and suddenly lost power. Got home and looked some things over.
All vacuums are intact and attached. (all lines were replaced with silicone lines about 4 months ago)
The computer is commanding/specified boost pressure but I get nothing over 1030 bar despite the ecu expectation.
In this chart, Yellow is actual boost pressure, Green is Specified, Red is Engine Speed Grey is charge control duty cycle:
In this chart you can see the ecu is expecting boost that literally never comes.
What could possibly be amiss here? stuck wastegate?
