seriously take the six phillips head screws out of the top the gate...watch because it will pop apart. you will see how that screw goes through the top half. and just kinda chills there. when the wastegate opens, it hits that screw.
if you look at the way it operates though, that screw does not interact with the spring in anyway. I think it gives you that one lb. of adjustment because it keeps the wastegate opening smaller. it doesn't interact with the spring though which is the actual way it controls boost.
I actually used that screw to controll my boost when i first slapped my kit on, and i noticed i was at a nice 5 lbs. of boost all the time, then i would start to creep to 8 and i was like WTF? So, i played around with it, and noticed the creep went away if i backed it out, but the boost was still 5 lbs.
So, i take the gate apart to clean it, like i have heard you need to do to keep the deltagates working good. (<-- don't really know if this is true or not). So, i am looking at this, and noticed the spring doesn't even touch the screw. It hit me right then why shawn complained of boost creep plagueing him with that gate. he had the screw turned in almost the whole way. now you find out that was your motor's downfall, so i know thats what his problem was too.
my word of advice is forget trying to use that screw to controll boost. either buy the right spring, or get a cheap MBC. i got mine for 30 i think. That extra lb. is not worth boost creep and a blown motor. And, if you see that you have boost drop off problems, which i notice every once in a while with having no screw in there, then turn it in a little bit, and see if it helps. just keep a good watch on your boost gauge.
