What are the limits to both of these stock components?
My simple research from questions and answers from this site are:

Stock BOV will start leaking in the 15s, so if your tune calls for over 15 lbs of boost, you should upgrade your BOV.
Stock sensor allows for accurate boost readings to the ecu for up to 17 lbs of boost, so if your tune calls for over 17 lbs of boost, this is also a must.

Please clarify if I am wrong or findings have changed.
 
My stock BOV was leaking at 15.4 lbs.

The stock map sensor reads PSI up to 16.8 lbs.

My wife was right! Even a new sled is a money pit!!!
I love my winder, but man o man, mod after mod after mod and when you think your all done, new mods come out
 
My stock BOV was leaking at 15.4 lbs.

The stock 3 bar reads PSI up to 16.8 lbs.

My stock BOV was only allowing 15.9 whereas the tune should have allowed for 16.7 lbs.
Added the TS BOV this season, so hoping to see that 16.7 !
 
Here it is....Think Ill grab one.

As usual Dan, nice info pic. You are a magnet for good photos with usable info.
This 3 bar map sensor is good for up to 28 lbs of boost. If you max this one out the 4 bar is next.

I put a cap on my boost psi of 16 a while back. Then I got the Max Spool 16 and was very happy with the 15.9 lbs that my tune was allowing. Then I found out it should be spooling to about 16.7 so here I go, gonna get there for sure, so if the BOV alone does not do it, I also will get the 3 bar.
