fluentfreak is on a distinguished road

I ran the LES pitzDaily tutorial:

The velocity field is ok. But the pressure field at the inlet fluctuates drastically which is propagated downstream to the pressure outlet boundary.
At one timestep the inlet pressure is +400Pa and after a few timesteps the inlep pressure becomes -400Pa.

Have you observed this problem? Can you offer any solution to that?

I have tried different integration schemes and more number of PISO corrections. But no lock...

Please help!
