To keep the emittance growth in the ILC main linac at a reasonably low level ($∆ε_y$ < 10 nm in 90% of all cases), Dispersion Free Steering (DFS) seems to be insufficient. In this report the use of emittance tuning bumps in addition to DFS is investigated. Simulations show that two dispersion bumps may be enough to reduce the emittance growth from 50 nm, after DFS, to approximately 10 nm, as desired. The effect of an additional wakefield bump is also studied giving very good results: an emittance growth of 1.5 nm or less in 90% of all cases. Furthermore, the robustness of the tuning bumps is investigated, showing that the emittance target is reached even in presence of noise during or after the bump tuning.
