2004 Subaru Forester

Engine Performance problem
2004 Subaru Forester 6 cyl All Wheel Drive Automatic 98000 miles

My car has never been the same since I had the turbo replaced a year ago. I brought it back to the dealer after the install explaining it now has no pickup but they told me it was fine and there was nothing wrong. A year later it has even less pickup. It smokes alot when I start it in the morning or if I havnt driven it for several hours but not when I rev it. And its been bucking between gears. I dont know if any of its related but I was wondering what might cause these issues. I just got a transmission fluid flush but it didnt help. I am a girl so I would like to have some clue of what may be wrong in advance so I dont get taken advantage of. Any insight would be of great help.
