Ok I have a question, if I buy a manual boost controller how does it work? I think I have a good idea but I need to know if I am right. This is my Idea: I have a2005 Evolution 8 and since my boost is 19psi at full throttle and then after so many RPMs it drops to 16 psi, BUT if I install a Manual Boost controller, if I set the MBC to 18 PSI then It will be 19 psi at full throttle and then drop to 18psi, correct? The reason I ask is because I was thinking of setting the MBC to 19psi, so it will be 19 psi all the way to red line. I just want to make sure that if I set it to 19psi that it isn’t going to be like 23 PSI at full throttle and then drop to 19 psi. AM I right though on how it works?

Also Is a MBC worth the money? and if so what brand is the best to use with no issues?
