2017 no boost

[Justin3773]

I have a 2017 802a raptor. I have it tuned from unleashed,afe cold air intake and Borla Atak exhaust. Today I got that code for underboost now I have no boost what so ever. Any ideas? Could a bad bov cause no boost or just low boost ? I visually checked the hoses going to intercooler etc. Ever since I added afe intake my turbo whistle has been very loud especially on cold start until I gets to operating Temp. Now no whistle at all no sounds from turbos

Check the plumbing?

Hi there yes I visually inspected all the plumbing I could see. Re checked all the hoses on the intake I installed etc. How could I tell if a wastegate is stuck or blow off valve gone bad any idea ?

I would also make sure the plastic cover in front of the intake is secure. People have had a tendency to suck those into the intake under boost. Other than that I can only think the BOV is stuck open.

Ok thanks will check that here is my setup. Is there anyway to test the bov? If it was stuck open would the truck build no boost ?

What does it do if you clear those codes?

 

[Justin3773]

If I clear the codes it goes right back to no boost. It will drive without a check engine light until I give it hard gas then wrench light and underboost code. I also put it back to stock tune same thing.

Bump anyone have any ideas ?

Ok so I dug into the truck I got the blow off valve out and it's split all around the green ? Would this cause no boost like I am having ?
