It is generally assumed that, if Sylar takes a power, he takes every aspect of the power. Radioactivity, for example, has EMP blasts that Ted performed. Sylar can most likely do it too.
But yes: Intuitive aptitude, telekinesis, cryokinesis, enhanced memory, enhanced hearing, radioactivity, precognition, and liquefaction are all powers that he has exhibited after stealing from his victims. Candice's power of illusions might possibly be in his inventory. Mohinder mentions more, which would bring his current total to ten (not including illusions). That leaves a possible three unknown powers.
