Do not turn it all the way down if you decide to mess with it. You have no way of knowing how rich it will end up. Take it to a dyno. That screw on top is just for fine adjustment. There is another adjustment internally preset from Comptech.
If you must mess with it, try 2 complete turns clockwise. That will make a significant difference at stock boost.
Also, do you have an ESM and is it a soldered connection?
How do you know its misfiring? Was there a cel? Did you gap the plugs before you put them in?

How do you know its misfiring? Was there a cel? Did you gap the plugs before you put them in? : I said its misfiring cause it sounds like it is. Im not totally sure if it is or not. Whats a cell? I gapped the plugs at 40.
this may seem like a stupid question but what was the gas level at: I have one bar and the gas light is on but there is enough gas in it for the car to start.

I would take it to a dyno and let them sort out your AF's before you drive it.
As far as stalling it sounds like it happens at idle or it won't idle?
Something else may be wrong.
Did it run fine for 100 miles and now it is running like crap/stalling?
When you start the car, can you keep it running by holding the RPM's above idle (2-3k rpm)? If so - does it sound like it runs rough or is it smooth.
A CEL is a check engine light. If you have one is it flashing?

White plugs are bad.
Rich is better than lean if you're going to drive to the tuner.
Stock the screw is ~1 cm exposed above the nut for general ballpark.
I'd buy a bunch of cheap copper plugs and pull them after another 50 miles and see how fouled or lean they are.
Obviously the optimal thing is to get tuned immediately, but sometimes that's just not possible in a daily driven car.
