Well directly after the vcg I did the ofhg. Not sure if it had this issue in between. The CP has already been replaced but I am going to double check my install today

Two places I would investigate. - First one is where the yellow arrow is pointing at. Check that connection and the other end where it connects to. (IF YOU HAVE EWG IT WILL NOT BE PRESENT, ONLY PRESENT ON PWG)
- Check the hose to the right of the arrow which is directly behind the oil fill cap. That crankcase breather hose connects to the inlet of the turbo. This could be broken or damaged, or may not even be fully seated.

Funny you mention that, we saw that hole during the install and were freaking out why there's no hose. I still need to verify that I have an EWG but there's def no hose so im sure I do. Will check that other hose today

Also, when you did the smoke test, did you pressurize?
Did you try unplugging the MAF? I thought i just linked the other thread with that procedure recently but let me know if you can't find it.

Is the CCV hose that second hose mentioned above? No we didn't pressurize, just put smoke in. And the MAF is the one on the intake right? We cleaned it but didn't try turning on the car with it unplugged. I'll try that as well
