Hi. Per the video. After my recent (couple weeks ago) VRSF FMIC install. I am getting this stuttering and power loss that sounds like a trumpet. It occurs at virtually any RPM, over a quart throttle, and between 5-10l+bs PSI. WOT just exacerbates the power loss.
As soon as I upload this thread. I’m immediately heading into my garage to perform a boost leak test. But I wondered if anyone has had this type of power loss and hear this sound before and what caused it?
I’m always glad to do the research & work but like Scooby Doo I’m always looking for clues. TIA...
