Start closing them earlier. I have been messing around with mine since I got them. If I want to smoke at 250 I run it wide open till 200 then completely shut the back vent (I light my charcoal in the back) and leave the front open till it hits 225, then close the front vent to halfway, then just before 250 I close it to about 1/4".
Also like Untraceable asked, do you have water in the pan? Mine definitely spike without water.
After finally getting used to manual temp control I used my cyberq II for the first time yesterday and it is awesome.
