as mlr is down its time to ask people who know about this stuff lol

on my evo my car runs an external watsegate, now for some strange reason i cannot get past 20psi of boost

my boost controlleris maxed out no more boost, it did run 24psi but since i had proper pipes madeup on the controller its wont do no more

but even then it will only do 24psi, so would this be the cause of my wastegate not being strong enough? i couldnt tell you what it is or what spring is in it as it was the car when i bought it, just know it says 38mm

if its not the wastegate then surely it cant be the turbo

im just stuck now as the car isnt punhy anymore, screamer pipe isnt opening either
