Default Loosing boost at high RPM

I'm loosing my boost at high RPM. I have an 8 pound pulley on the SN93 and I drop to about 5 psi when I hit my shift point at 6k. The car does have a steeda 19 cam and 1.7 roller rockers so my lift is higher than stock. I also have a 65mm tb.
Is it possible I'm out breathing the supercharger
thanks guys

Default Re: Loosing boost at high RPM

Sounds like belt slippage.
