A bigger turbo can result in less smoke on the top end and significantly more smoke on the bottom end if not tuned correctly. Tuning is the key with either setup.
Look at the settings on the smarty and see if you can find anything related to low end response, otherwise you'll need to buy the Quadzilla like others suggested. Then research and learn how to tune with it, some trial and error will be needed to tune your individual setup.
