For the past 2 weeks Ive been seeing blue smoke at idle and under boost, so on my day off I decided to do a compression test.
#1-150
#2-152
#3-150
#4-150

I know that the standard is around 160psi, so its a little low but what should I think is causing this now..Should I go ahead and perform a leakdown?
 
It can't hurt to do the leakdown. Your compression numbers look fine; have you checked your turbo for play?
 
those were my compression numbers exactly so your good to go! i 2nd the whole check your turbo when my 16g was blown thats when mine smoked like that
 
You just answered your own question.If it is still smoking at idle with the turbo swap,it's got to be the valve seals.They are not hard to change if you have the right spring compresser
