Intermitent Power Issue

[EAST TX SHO]

Started noticing when I'm at highway speed and I floor it, the car doesnt surge forward like it used to.  Seems to be a slower pick-up in speed.... holding gears longer.
Took i to the dealer - their transmission guy couldnt find anything wrong.... no error codes, etc.
Seems I can hear the BOVs more pronounced that before.  Low speed acceleration doesnt seem to suffer.  ALWAYS burn premium gas, have even gone thru a couple of tanks in case it was a bad batch of gas.
2015 PP with 47k miles. Stock car except K&N drop in filter.
ANY THOUGHTS?

Any fuel smell?  To eliminate injector/cat issue.

No codes?  No other symptoms like jerking/bucking/etc?  If the wastegates are malfunctioning, you would expect to get some over/underboost codes.  Check turbo piping for loose/cracked hoses.  That includes the smaller hoses on top of the intake manifold.

THANKS for the input SHODDed,
No smell.
No codes, no jerking.
I'll check the hoses

My car didnt throw codes, but was underboosting. Would try to make peak boost for ~ 4 seconds then ECU would shut it down. DO you have a boost gauge or way to monitor? I came to the conclusion a wastegate was stuck, was going to look into it more but got ran off the road so I'll have to fix it after I get the car back.

FINALLY. Found a disconnected vacuum line- 1st one behind front BOV. hearing it's a common problem.... no clamp on it. Wasn't allowing turbos to come to full boost... so it was more noticeable at higher speeds. Checked the wife's 17 Explorer Sport.... hose already starting to slide off. $45-$50k vehicles each.... can't ford spend another 20 cents?

Nope. LOL.  Glad you found the loose tube.  So all is fixed then?

Runs like new! I appreciate everyone's help. Damn techs at Ford dealership see so few SHOs in a small town, when they test drive they don't know what it's supposed to do. Both my vehicles have the same engine... guess I'll be the new expert in town

I know what you mean.. took mine in and told the service writer that I had a noise that sounded like a drivers front wheel bearing going bad. Under warranty btw.. he said they would check it out.. well long story short after 5 trips to the dealer I ended up with both axles replaced, and two new wheel bearings. The last thing they replaced was the drivers front bearing which fixed the issue. Long story short I got a totally new front end basically at no cost to me other then the aggravation of taking it to them 5 times.

Its sad to say but most Techs are only trained to follow TSB/SSM Protocol and are not to well versed with this platform with the exception of the F-150 IIRC. but glad it was an easy fix and you can get back to enjoying the SHO of a lifetime. Z
