 The new simplified version of the piezo-assisted Blade Tuner has been tested at DESY in the horizontal cryostat CHECHIA in September. The tuner mechanism has been characterized at room temperature and one high gradient cavity of the last production has been recently tuned and equipped with a properly modified helium tank. In view of its possible adoption for the ILC, the cheaper stainless steel version of the tuner has been chosen for the cold tests. In this paper the results are presented and discussed.

 The Free-electron LASer in Hamburg (FLASH), operating in the VUV wavelengths range, is not only the outstanding research facility in Europe, but also the test bench for the ILC superconducting linac technology. Started XFEL, as well as planned ILC, both depend on the progress made here. [1], [2], [3]. New module test stand was recently put into operation at DESY. The FLASH linac has been upgraded to 6 superconducting modules. The accelerating modules testing experience and the results of the tests are put in the base of this paper, describing the recent developments of the XFEL / ILC technology.
