Power pulsing, noticable under moderate acceleration

[mayo]

I've spent the morning running around in my 1.6l Ecoboost transit connect and forscan. Posting here because I cannot find a more appropriate forum for this engine.

Symptom:
A few weeks ago I noticed pulsing power when I am moving from 2000-3500rpm, I assume this is when the turbo is kicking in. If I am on a hill the problem is worse.

Vehicle Details:

• 135k km
• Oil Changes every 5k km
• Transmission fluid changed at ~70k km
• Air intake filter changed often, just changed it again
• Spark plugs just changed (Motorcraft SP532X)
• Borrowed a forscan scanner and have been checking various sensors and readings (attached)an
• No codes shown even after many aggressive runs

Possible Solutions (data gathered so far):

• VVT (variable valve timing) solenoid
• Wastegate solenoid

Thanks everyone. If you thing some other data points can be grabbed I will jump in the truck and try it out

Alright guys, so I took the first, simplest approach of changing the waste-gate actuator solenoid (PART# CJ5Z9K378B - Turbocharger Wastegate Actuator). It was a bit of a pain in the ass tbh. Went to a couple of mechanics who both suggested I change the catalytic converter, no mention or hope in the waste-gate. Even the Ford tech I visited didn't think it could be the solenoid, said they haven't seen readings like those posted above without a code posted, they looked a bit bewildered, which probably lead them to suggest catalytic internal failure, as it could happen without a code posting.

Well it turns out IT WAS the wastegate solenoid. I went OEM, did a couple of runs with forscan and then reset my transmission adaptations and did more testing, results attached below.

I hope this helps someone in the future. Another tip, make all your clamp connections before putting the actual solenoid in it's fixture/tab connected to the engine.
