Hello, I have a 2013 Police Taurus with EB engine 135K mi.
The power seems strong, however sometimes I hear a squeal that sounds like a belt slipping at WOT. Not every time, no CEL.
I also sometimes think I hear air leaking at sporting throttle (not WOT) and hear a little poof of air when I let off the gas. Is that normal wastegate opening?
My only turbo experience is my stock 2007 LBZ Duramax, that seems to just spool up and down in a predictable way.
I have no experience with small twin turbos so go gentle on me!
