2012 F150 3.5L FX4
Turbo wastegate actuators.
Both where reading on gauge cracking pressure was 6-7 (should be 3-5 supposedly)
Max open reading was 12-13 (should be 12-15 supposedly)
New reads are cracking at 4-5, and open at 14.
So, slight difference but that's what fixed my issue.
Only by a couple psi each actuator.
Replaced both, and problem is fixed.

Hey all. I'm brand new to joining this forum. Although I've been coming to the site in and off for the past 2 years for insite, as a lurker lol
Truck Is all stock
But I'm having issues with my turbos:
- NO CEL but p0234 stored in computer (overboost)
Coming from a red light or stop sign I get a "wooshing" sound like "wooshwooshwooshwooshwoosh"
If I really get in the gas It will stop and seems to boost properly
WHAT I'VE TRIED:
- I've checked the wastegates, they are not seized, pressing in the arm that the actuators connect to they will open and close.
- I have very LOOSELY attempted to inflate the actuators, they will inflate and open the gates.
At a very low setting on my compressor tried roughly 7psi the passenger actuator will move, the driver side requires a bit more but will open. (Whether they will hold air I don't know, don't have a pressure pump)
- Today replaced the turbo actuator solenoid on top of the engine with a brand new one from dealership, hoping it would be that simple, is not.
My guess as to what is happening is possibly the driver side actuator is not set correctly or equal pre load to the passenger side.
And the driver actuator would be opening a little later and kind of fighting each other if it's trying to close while the passenger side is opening?
Could that be correct?
BOV'S sound like they're venting properly, prompt and stable release upon deaccelerate.
I have seen the new actuators available on fullrace(?) But not thinking I need them
Been having this issue for about a year.
Any one experienced with turbos and DIY willing to help me out or even give your thoughts much appreciated!
( FYI I am poor and dealerships are not am option lol)
Tried posting a short video of the sound but no luck. Sorry
