no matter where the mbc is set, my boost wants to rocket up lol

set-up is a boost logic 6176 pretty much stock otherwise, this setup ran 100% on my other evo, only thing changed was the wastegate (upgraded to a tial mvr) also running a 18psi spring in it.


all my vaccum lines are good (i think) 99% sure and everything else is fine.

is it possible to have to much spring in the wastegate? shooting for around 30 psi

any other help would be appericiated
