Car felt about the same as last time. Pulls were made at 9500 feet.

Pulls were made at 9500 feet. I forgot to disable DTC but I do not believe it came on during any of the pulls. Happy to re-do if necessary, just let me know. Did not throw any codes. Still felt strong but I can tell it’s making less power than the v2 map was at 5500 feet. Drive-ability is good but I am still getting some compressor surge when letting off at low rpm/boost. I am also getting a strange “inhale exhale” noise from the BOV when driving under partial throttle at low RPM. It sounds cool but I’m not sure if that’s supposed to be happening.
