I am going to keep shut because I keep confusing the two. So, if any leaks occured, the boost will just be reduced. Correct?

The compressor should overspin because the flappers aren't open until XPSI is met (Per my EBC). So, it's overspinning, I was outside the compressor map and power took a shit.
I didn't notice the lag actually but I have talked to a lot of people about this as I am against those that think they can tell if they have leaks. I think that's complete bullshit. However, there are soo many ways to modify "lag threshold" (Starting at 2,500RPMS and building more initial load is one way off the top off my head) that I didn't really do much thinking about it. I thought it was a bit diff but that could have been my ass dyno.
