can anyone tell me why my boost drops on e316g?

mods in profile adjusted mbc a little bit because I thought it might have been closed too much but i guess not. heres a log any sugestions would be helpful. car was hittin 20 psi in 2nd gear and 28 psi and dropping in third gear.

You need a stronger wastegate actuator. The factory spring tension is somewhere in the neighborhood of 11psi; there's no way it can hold even a standard 31mm flapper shut throughout the rpm range at 28-30psi.

I couldnt just use a stronger spring? My cousin said he has a spare 19psi spring for srt4
