But then boost decreasing from 15 psi peak to 11 psi towards the 5000-6000 rpm.Is there a way to reduce that effect? Air intake or waste gate actuator or something else?

Get an actuator with the spring suited to what boost u want to run, so for a 15psi tune you should get a 12 psi actuator, you could get a 15psi one but you won't be able to run less than 15psi.. Unless your happy with that..
