its ingame programing, the chip is not pulsing slow, its pulsing at 50sps per second as you set it to do, whats hapening is the game can only see every other or every three pulses because its happening so fast. slow it down and find the right speed for the right game. more is not always better. MW2 is best at around 11 sps using the fal, after that it will start to spit and studder, slowing it down. try to use a sinwave (WAW setting) and speed it up that may get a few more sps out of it. but I doubt it.
