EOS switches are not as important on a Fliptronics machine, which is what you have. Rottendog boards are fantastic and they provide excellent customer service. I installed one a WCS 94 pin and have had no problems.
Getting back to Getaway, I also recently acquired this game, and really enjoying the fast pace of this machine. Anyway, have you rebuilt any of the flippers. This is what I had to do to mine, and it made a huge difference. Also, check to see that the right coils are being used in the game, and replace the sleeves also.
