yeah i know you can't turn the boost lower than the wastegate spring... I was simply asking if I should buy a manual boost controller or a 11.46psi spring for my wastegate... right now I have a 7.25psi spring in there... and I was asking which would hold steadier....

The manual boost controller will be a little more steady than just off the spring for really low boost like that. just rock the spring you have for now and get a bigger one when you want more than 300whp

everyone answered no because they are right. you cant make a spring less stiff (less boost). but you can manipulate the amount of pressure it sees, thus opening later (more boost).
