I recently noticed a squeaking sound when decelerating on the car when in gear or letting off the throttle. It is a high pitched sound and happens when letting off power or when using gears to decent down a hill instead of braking. It can be heard in the attached video after letting off the revs and goes away back at regular idle. Any thoughts?

Wild guess would be belt or something alternator related.
the belt would be my first check.
Almost sounds like air going through something. If the belt isn't causing it, look at your decel valve to make sure it's hooked up correctly.
You can stick a vacuum hose up to your ear and put the other end in various spots in the engine bay to see if you can isolate the noise.
