He's probably using a tweecer or tuner to adjust the dash pot, surging idle is usually caused by a rich condition. The idle adjuster plate which was mentioned works well, but a side effect on some applications has been a hanging idle when revved, a small price to pay for a steady idle and no stalling IMO. I had one on my car and it did cause the idle to hang a bit, but then I changed a whole bunch of sensors all at once and most of my problems are gone. I did have the surging, but now I'm down to just running slightly rich which I can sort of live with lol. I may try the idle plate again just to get the idle up a little, 700 with underdrive pulleys doesn't allow much charging at idle, and it seems to load up the motor running at that low as well with the X303 cam.
