Airfoil - Over Estimation of CLmax with FLUENT

Hi, I am validating the aerodynamic coefficinets of airfoils from FLUENT against experimental data. Test conditions of mach 0.35 at chord Re of 6.0 million are used. With the three airfoils that i have tested, FLUENT over predicts the Clmax in all cases where the onset of flow seperation is not accurately captured (is overpredicted). I am using the k-w SST model with two fluid zones given that the BL tranistion point is known from the experimental data. How can i rectify the over estimation of Clmax???? (I believe it could be my BC's..in particular the inelt turbulence intesity factor...however i am not sure what a suitable value is...) Thanks heaps
