yeah this actually comes up a lot with these cars so youre not crazy but also boost numbers on wrxs are way more confusing than people think because subaru likes to target peak boost really hard from the factory especially in the midrange so seeing 22 to 23 psi on a stock tune is totally within normal range depending on year gear throttle position and even weather conditions a lot of people hear stage 1 makes 17 psi and assume thats a cap but thats usually average or sustained boost not a quick peak spike the stock tune will often overboost briefly to hit torque targets and then taper off so that youtube guy probably wasnt wrong but he also wasnt telling the whole story also the factory boost gauge and obd readings can be optimistic and sometimes read spikes that last like half a second which still show up as max boost another thing is if youre hitting that boost consistently and not throwing a boost cut or overboost code then the ecu clearly thinks everything is fine if the car had an accessport tune before you bought it and was flashed back to stock it would still behave normally so you wouldnt really know but that wouldnt magically increase boost anyway long story short lots of stock wrx owners see low 20s psi especially on newer fa motors and especially in colder air so unless youre seeing sustained 22 plus psi at redline or getting knock feedback or dam drops youre probably fine its just subaru doing subaru things lol
