new turbo problem

just spent $3000 to have turbo replaced at detroit diesel, climbing hills seems to take a good 5 seconds for turbo to start boost, engine sounding much louder than before when climbing hills, also pulled out of truck stop truck had very little power then after 5 seconds or so the turbo came in, they fitted new turbo/actuator, now have vpod air leak, any ideas please, 2005 s60, 600k
Thanks
