Does that help?
Sort of.

The reason for my confusion stems from what was told to me by a particular mechanic. He stated that stage 1 BM3 adds 4-5 PSI of boost. Seeing as stock boost for the n20 is (I believe)16-17, I thought his estimate was a hair high. Similarly, I was surprised to see a target boost of 17-19 given to me by PTF, considering 17 is nearly identical to the stock boost target.

I feel like I am missing something here.

Just trying to learn!
