what does it take to drop a pulley, mechanically? Do I just go buy a 2.8 pulley and it bolts up? I know the tune will need adjustments.

Yeah I know that, but how do you get the 3.34" pulley off? I'm a 2.4 s/c. Forgive my M62 ignorance, I never paid attention to the 2.0 threads until recently. Do you need a new hub to get the 2.8 to fit?

Yeah, Im from Charleston SC, so pretty much sea-level here and on cold nights, i've seen 16.5-17psi on stage 2 only, but as everyone says, depends on a lot of variables.

Yes you must take the belt off, the tensioner is right next to it looks like a little shock absorber with a pulley on it, a little notch next to it 15mm wrench push it back towards the firewall!

then when the wrench slips and you smash your hand into the valve cover a couple times. you will remember to do it slow, and put a rag ontop of the wrench to soak up the blood that is now oozing from your knuckles.
