So I installed a PRL Big Turbo kit, got no CEL initially. Took it to the tuner, stopped it from trimming all the fuel, but now it's throwing a CEL, code P0046.
I've manually adjusted the wastegate (WG) and it appeared to be all lined up with the commanded value (WGCMD), as you can see in the above video. Then, when the WGCMD was telling it to close so I could make boost, it breaks. After that point, WG and WGCMD no longer line up.
I attached my calibration and some datalogs.
Any ideas?

Re: Diagnosing my Wastegate Actuator
I would contact PRL for advice on how to properly adjust the wastegate.

So I have contatcted PRL, but they've been mostly unhelpful. I'm just covering all my bases.

Turns out it was a mechanical problem. The clip on top of the wastegate actuator arm was binding on the intake pipe. Changed the orientation of the clip and she's making boost and running smoothly!
