Intercooler Leak? Limp Mode

Anyone know if the Ambient Tempature Sensor could be any cause to this? I know for certain this sensor is unattached - I caught it on a video when I was doing the intercooler hose repair.
I’ve read about this sensor in a few different places and it’s unclear if it only affects A/C performance.

If it's disconnected, so open circuit, I believe the dash outside temperature display defaults to 185F. It may cause limp mode.

Here it is - I pulled it out from inside where the front plate should be. Tested and reads as it should when it is affected by a heat/cold sorce. Dash temp reads 60F+ after plugging back in so I don’t think this is a contributor.

That is the sensor and its wiring, looks intact to me.
Yep, it was. Tested it and read as normal.
What does the Ambient display on your dash read?
The display read 60F+ and when up just 5 degrees when driving a short distance.

Here is a video below looking at the turbo: https://we.tl/t-6XI6HMdA8x
Here is it whistling past 4/5 RPM at idle:

Anyone notice anything out of usual? Will need to get a closer look but the arm looks to be functioning when starting and pressing down on the gas.

sounds like a potential boost leak in the last two vids... more vids with more revving the motor up.. chalk the wheels, put er in reverse, pull the ebrake, left foot on break, make sure nothing is behind you.. push the RPMs up for a bit (more than for just a second.. like five seconds...) a couple times..

Will do. I’ll post the video as soon as possible. Thanks for your insight
