Nothing has changed but you've touched a lot of stuff since the tune (turbo,injectors,the actual tune,plugs). You need to go back over what you touched. Maybe the injectors got messed up with you cleaning them. Maybe a spark plug tip got bent. Swapping a turbo isn't going to cause the car to run rough and not rev over 4500 in neutral.
