Another newbie question about Boston Butt

Just put on a 9lb butt (my first butt) hoping to pull at 4pm tomorrow. I obviously put too much lump in- I cannot get the temp down to 250 even though I've basically closed both vents. From reading around it seems opening the BGE is treason. Any suggestions would be greatly appreciated.

    How long has it been on? As long as it hasnt been on too long, I'd take the meat out and start over. If you leave it in, an hour or so at high temp wont hurt a thing. If you cut off the air, it will cool down eventually
    Be careful, man! I've got a beverage here.

    Probably not an issue with the quantity of lump in the egg, but how much you have lit. If you get too much lump lit in the beginning it's hard to keep it low. Don't leave the vents/dome open too long during the lighting process.

    Too much lump is not the problem, there's a million different ways to light the egg.  I usually take two starter cubes and cut them in half put one in the middle and then put the other three two to three inches out in a circle around the middle.  Open everything up and raise the lid for about 15 minutes.  This way works for me.

    big issue is that the fire was above 250 in the first place.

    as others said, it's not how much fuel you have, it's how much you are burning.  just as a car with a full gas tank does not go faster, a full egg won't burn hotter.

    don't let temps get established for any length of time above your target temp. one of the ways the egg maintains steady heat is by sinking so much heat into the ceramic. which means if it is allowed to get hot, it'll stay hot.

    only option for a too hot egg is to shut the vents down. even barely open, it will not choke out the fire.

    On my XL, to hold 250* my bottom grate is only open 1/4" to 3/8" and my daisy wheel is covered with the little holes open a about half-way.  I thought for sure I'd kill the fire the first time at 1/4", but worked fine for hours.  Like Stike said, once you overshoot it takes time, like an hour, to come back down.

    I would not be concerned with hitting 250* dome temp for a butt.  It will come out just fine at 275* or even a little higher.

    During a low and slow if mine gets too hot, I have a routine that seems to work. I close the bottom vent to about a sixteenth of an inch and the same with the daisy wheel. I leave them like that for about 20 minutes to slow down the charcoal burning. Then, I open the top vent as far as it will go for 30 seconds. Repeat as many times as necessary. Doing this kinda sucks, which is why I've learned to pay closer attention to the temp during the initial startup. Depending on how much too hot the egg is, I will burp the dome lid for a second or two. 

    The idea I have behind this is to slow the charcoal burn and let the heat that is built up inside the egg escape. I know you should never open the dome lid, but I believe you have to make these mistakes before you can learn from them. I've never had anything come out bad from doing this or from not doing it. I'm sure there are a lot fo crazy routines out there that make no real sense like this one!

    be careful burping the egg to 'release heat' if you are around 250 or so.

    the only thing that cools off is the thermometer.  the egg ceramics will remain hot, and worse, the fire (which is very very small at 250) will get a nice big dose of fresh air when you open the dome.  think of how small a vent opening will maintain 250.  tiny.  then imagine how much bigger the 'opening' is created by opening your dome.

    just shut vents and let her come down.  if you are at 300, better to not even shut vents too far.  just set them for 250, and it will eventually get there.  if you overchoke the fire, you'll submarine under 250 and then need to fiddle with vents to gt back up to 250.

    the zen approach is that maintaining a certain temperature is achieved most easily by not trying too hard to maintain a certain temperature.

    A butt is so forgiving that cooking a bit higher than 250-275 is fine...won't wreck your cook.  I often cook butts or brisket at 300 on my offset.

    Thanks to everyone. I got it down in the 225-250 range for about 13 hours and it was delicious. Can't wait to experiment with ribs, fish, etc.
