When I punch into boost, I get a strange squeal.
Sounds like a cross between a boost leak and a squealing belt. Doesn't happen every time, but I'd say 80% of the time.
Happens right around 4K rpm.
Some notes about the car:
TMIC never removed.
ZERO mods whatsoever under hood.
Only mod is a CBE.
under 30K miles.
Sound in't great in the video, but you'll hear it clearly on the second pull.
