Boost and RPM's

I've got a cobb stage 2 setup and wondering about boost drop off at high rpms. I'm getting between .09 and .1MPa from 3000 to about 5500 rpms, then the boost fades down to either .07 or .08MPa. Is this normal or should the boost stay constant to redline? :?:

Thats normal. Boost tapers off towards redline usually.

cool, I wasn't sure if I had a pressure leak because boost is fading off a little. I was getting .1MPa this morning. Thanks for the info
