I would second this.
In my case got horrid wastegate rattle (because they are worn bad which was masked by the old software).
Re-adjusting the rear rod got rid of most of it (not completely) but the car feels so much better without lag. Drove like 3 yers with lag without knowing it, now car performs soooo much better.
Just use ISTA /P with retrofit option, since adding the d-(or K-?) word via WinKFP doesn´t do the trick (missing the proper DME maps I think)
