New Pulley Boost Pressure Lower

[mustangindy33]

Over the weekend I changed out my 3.6 Pulley for a 3.48 pulley. I have a 2016 with a Paxton, with the 3.6 I was running 12-13 psi with mechanical boost gauge. Now with the new pulley I'm maxing out at 10 psi. I've checked all the lines, installed new belt (tight) and I've found nothing. Could it be the BOV? Now the BOV sounds like it's leaking, it's blowing off at idle and with very little throttle. What is the Paxton Max BOV rated for as far as PSI? Do I need to adjust from the factory settings?

the bov has nothing to do with boost unless it’s open during wide open throttle.
More than likely belt slip
