Sound Synchronization isn't an issue with diesel Loco's. Stick with QSI or Tsunami and you'll be happy

I am going to second this vote for QSI or Tsunami.  Those two are the best choices.

Take some free advice and avoid any MRC sound decoder. They have a history of failure after only a short time of use.

i have an atlas gp9 that is desiring a drop in sound decoder that synchronizes sound with loco. does mrc make one that will fit without any altering of frame.
