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

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 ?

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 ?

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.

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 ?
