Squeal high pitch whine under load

Just installed Cobb ap 91 octane. I've noticed often under heavy load when letting off gas to switch in and out of 3rd maybe 2nd gears I get a slight high pitch audible squeal. Anyone know what this could be? Is this normal?

I just wish I could get a little cheese with that whine.
