I've been running the RiffRaff boots for a while now with no issues.
IMO, you need to figure out the screeching sound. As you posted, the boots were fine until you started hearing the new sound. Do you have a way to monitor boost? I'm not familiar with the BanksPDA.
Are you still running the PCV? Inside of CAC tubes oily? I had terrible problems blowing off the oem boots. They'd get oil soaked because of the PCV system allowing an 'oil mist' into the intake system. By the time Ford figured out they needed an oil resistant inner layer on the boots/hoses, I'd already moved to the RiffRaff boots.
Anyways, I'm betting you're overboosting....
