Power loss after running

[nikhsub1]

I don't think you should hear blow off valve even after let off since it's not an after market blow off valve type but actually a recirculating bov ...thoughts ‍

Agree, I could never hear mine when the truck was stock.

I should have been more specific. When this first started k thought it was a bad blow off valve so I replaced stock with a turbo smart that vents to atmosphere.

Ah that makes sense.
Is there a chance it is defective or maybe something came undone or loose? You're definitely on the right path with the boost leak imo

The problem started before I replaced the valve. That’s why I replaced it. I’m not sure it has to do with a boost leak. When it does it, it still builds boost and vents, but feels like the turbos aren’t working

I had this happen to me once. Boost was being made and registering on the dash, but there was very little power. My only thought was that the BOV got stuck open.

Very good possibility

which on the surface seems to rule it out but ...

NEVER modify a truck with a known problem or issue ! ! ! !
Your troubleshooting becomes exponentially more complicated the more mods you take on.

Now that I think about it My son had the same issue on his ford focus st. It was the plastic pipe intercooler piping that came loose. Check all intercooler piping and make sure the clamps are tight. If the problem was there prior to replacing the BoV chances are it's an intercooler pipe that's loose.

I don’t think it’s innercooler piping because they seemed okay when I removed the innercooler for the BOV but I’ll check them again.

it's just weird man, are there any codes?
I just can't imagine it's the turbos but you never know. Also sounds like when your catalytic converter is clogged but I can't imagine it could be that already. Gotta be something dumb. Have you tried doing the throttle reset? Not sure it would help but there's a trick on YouTube where you turn the key on, push the gas pedal down slowly and release quickly 5 times etc..and most people reported it helped their performance, response acceleration etc..
It's a long shot but who knows.
You're using 93 octane correct? I know people say todays turbo vehicles run fine with 87 octane blah blah but I just don't agree, if they do it not for long and you're not helping the engine. Anyway I'm sorry I can't be more help here :/
