Welp following up, went back to 91 to eliminate any fuel trims from that, and had a buddy come over Saturday night to troubleshoot. Installed my boost leak tester, pressured up to 5 psi and you could hear a faint noise. Went to 10 and it was very apparent that we had a leak.

Turned out the boot T-clamp popped off the rear turbo which was affecting wastegate readout. All fixed!
Follow up ? How do you test for boost leaks on a twin turbo setup like the SHO? I've seen some YouTube videos where you cap off the turbo and pressurize everything but assume you would have to do it to both turbos? Or is there another way? TIA

There are many reputable shops that perform a Smoke test! Bottle of soap is another alternative with water preferably kids (Mr Bubbles) and spray around the engine bay until you notice any bubbles forming. Z


Here's the PIC of the TURBOCHARGER VACUUM HOSE LINE TUBE AKA - Rubber Valve Assembly as mentioned earlier for reference..I'm just TOL

Thanks *. Well my car is actually running just fine now stock. It fixed itself at some point which bugs me even more. I'm leaving it alone for now although I still feel the wastegates duty is high to maintain stock boost levels. I will probably go back to tunes and see if it can keep up.

I guess you can always try to (pinch) the wastegate hose leading to the wastegate with locking pliers in order to determine if one of your Turbos are going bad!
If you notice the Boost level is back to normal during this procedure then one of your turbos need replacing and remove the pliers..

I would also try to rule out a plugged CAC.

It's a bit of Trial & error and proceed with CAUTION rule may apply!!  Z

Thanks Z. I've been patiently troubleshooting the last week. I've ruled out the TIP and MAP sensors unfortunately because those would have been easy. I took my air compressor and pressurizes the hose leading to both wastegates with about 12 psi and both wastegates moved and I verified there weren't any slow leaks so the hoses and connections are solid. I got both wastegates to physically move however the back one make a slight noise which makes me think it may be sticking.

I do have some general questions I'm hoping someone can answer specific to the Ecoboost. Are the wastegates normally closed or open? I know when the car hits 100% duty cycle on the boost solenoid that  I thought it was sending boost to the wastegates to close them fully so the turbos spin up. Since these are pressure actuated that would mean they are open normally? Or am I getting this backward LOL...

Unless the boost solenoid is bad I most likely have a sticking rear turbo wastegate.

The wastegates should be in the closed position AFAIK!
In your case it sounds like one or more wastegates are maybe stuck open or sticky wastegate.
The noise your hearing could be related to your issue!
I would also try to disconnect the PCM connectors and inspect the wiring harness for corrosion and clean it with some electronic or air mas flow cleaner.

wastegate at 100% is the pcm requesting boost and closing the valve to prevent movement of the actuator.
0.00 is rest position, or just wastegate spring only

(this is the way it was told to me)

Thanks for the reply and this makes total sense. I guess I was thrown off by a few posts on the other forum which said the c clip fell off their wastegates actuators and they had low boost. I thought to myself shouldn't they have high boost since the wastegates wouldn't open? Anyway I've ruled out the TBCP (TIp pressure sensor), the MAP sensor, IAT sensors, and the turbo charger boost solenoid, the BOV's, along with the lines that lead to the wastegates. I either have a big boost leak someplace (which I can't hear) or the wastegates are sticking open. I believe it's the latter unfortunately because the back one makes a weird sound when I artificially open it with compressed air. I've got an appointment at the dealer next Friday. I may have a local shop throw a boost leak detector on it first just to rule that out but I do have hot pipes and they seem Rock solid as I've checked the boots and clamps...

Wait a minute I think I get it...if the c clip pops off then the wastegates spring is still in play correct? So you'd see some boost but not only up to spring pressure...

Upon further review I've definitely found a problem. The front turbo wastegates actuator is no longer connected to anything...Its buried under the exhaust manifold and while I can get my fingers under there I can't get it from the topside by feel. It might be missing an entire pin and clip? Here is the only shot I could get of the end of the wastegate actuator attached to well... nothing from what I can tell  The rod also has play in it up and down which further adds to the it's not attached ..maybe I can get to it from the bottom?

Thank you!  I am going to have to buy some different sizes and see what fits but that should get me close.
