Default Hesitation in part throttle MY03

I have just updated my software to 4.2c, and the boost set at 16.5 peak. Right now I am having a problem, there is a buck or jerk or hesitation at part throttle between 2600 to 3300 rpm. I have a 03 wrx, I don't know if I am in olf or clf, but is it possible to use just clf and not olf?? How do I cure this problem

Sounds like the dreaded transition point between ECU and UTEC. First thing is to determine whether you are in clf or olf. Go into your Utec and determine whether you are olf or clf. Then post again with the answer.
