To much boost?

The x4 can log Tip, that's one of the parameters Torrie logs.

I Anybody know if the EB uses a bleed type control circuit?

With a bleed type circuit, there's a pressure source from downstream the turbo compressor, which lands on the wastegate actuator, which then actuates the wastegate linkage, opening the internal flapper in the turbine housing.
There's a electronic solenoid valve which is T'd into the pressure tubing. The ECU sends a duty cycle voltage to the solenoid which then actuates a valve, bleeding pressure away from the waste gate actuator, and back into the intake tract, upstream of the turbocharger.

If any part of this circuit is malfunctioning, there may be a spiking or over boosting condition. I'd imagine the gate flappers themselves aren't sticking, as the turbos are internally gated.
There's various, small tubes plumbing all of this s*** together which can rot, or pop off. The actuator itself can malfunction. The solenoid valve may be sticking. The coil on the solenoid bad. The electrical circuit could be malfunctioning...

The bleed type circuit sucks, becasue there's no failsafe, other than the ECU cutting fuel or closing the throttle or whatever. It is mechanically inferior to other methods.

Even still...I'm not sure what the EB uses. I'd presume bleed type, like most other OEM.

Vacuum Actuated Wastegate System
The 3.5L GTDI was introduced with a mechanical-pneumatic boost pressure controller as described in the previous section. Boost pressure is limited mechanically via a diaphragm and spring. Boost pressure can be increased within a limited range by controlling a wastegate pneumatic solenoid.

FoMoCoSHO

The following conditions may result in overboost.
One or more wastegates stuck closed
One or more control hoses leaking/disconnected between wastegate diaphragm and wastegate vent solenoid.
Wastegate vent solenoid stuck in vent position
Control hoses to wastegate vent solenoid swapped.
Hose between boost volume and wastegate vent solenoid disconnected.
Not-yet-detected Turbocharger Boost sensor in-range failure.

The boost control system computes a desired boost based on operating conditions. Via the wastegate pneumatic solenoid valve, it varies the boost pressure limit to achieve its desired boost level (measured by the TCB-A sensor). The air charge control regulates the throttle to control the intake manifold pressure (MAP).

You should throw a DTC if actual boost exceeds 4 psi of commanded, PO234

For what it's worth I had some symptoms which prompted me to bring the car to the dealership. They diagnosed and found I had a vacuum leak at the high pressure fuel pump at a vacuum line that was not clamped originally. This caused an over boost condition and threw a code.  They trimmed the line and added a clamp which cured the issue.

I forgot to attach a vacuum line to my intake before. When I started the car the turbos went crazy spooling up then dumping boost trying to maintain something. Not that this helps anyone. Just found it an interesting reaction from the car.

Like Larry Lu mentioned that there are numerous 1/4 vacuum&breather hoses in our cars without clamps,what i personally did was ordered pack of ten 1/4 clamps and installed them through out the engine bay for added security purposes.

I like that you got red ones. Makes it easier to spot where you put them!  Thanks.

Nice touch, ZSHO, carries the red theme into the engine bay quite well.
