Default weird noise at WOT

i have a automatic wrx vf30 setup with a perrin fmic, and yesturday iw as flooring it and all of a sudden around 6grand i hear a pshhh noise and my boost spiked to 17.9 psi, wich is fine cause im supposed to boost around 17.5-18..........

but what is that wierd noise, and also when i am around 2k and i take my foot off the gas i hear a wierd flutter/pshh noise from the passenger side
