Compression #'s, is this good or should I be worried?
1-200
2-195
3- 180 -I had to crank about 10 times to get up to 180. The others I cranked about 6-7 times to get up to 200 easy
4-~195
What do you guys think. Should I chill w/ the boost for now, or are these not that bad? What can I do in order to fix #3, and how much of risk am I at right now?

You should be okay, how many miles are on your car? 180 I think is on the border of being low.

Right now the ZC has about 45k-50k on it. #3 got topped out at right about 200 when I cranked about that many times, along w/ the rest of them.

you take your highest comp. # and if the lowest one(comp. #) is not within 15% of the highest # you may have a problem.

Or if you don't have a leakdown tester or compressor, try putting oil into that cylinder immediately before cranking. Look for a compression jump as the oil temporarily improves compression. Not exactly conclusive, but it's easy at least. 
How come it's #3 that's the problem more often than not...must be something in the geometry of our engines.
