exhaust flap not working + boost leak code

from past few days, my car seems to have both exhaust open all the time. vaccum is plugged in and i have taken it out and put back in but both exhaust sides still stay open all the time.
while doing WOT yesterday, i got half engine light with codes for boost leak. 3100 i believe. before that or since then car pulls super strong.
vacumm not working and the boost leak code , are these issues inter-related??
how do i go about fixing it or where to start troubleshooting from??
any useful input will be highly appreciated. thanks

3100 is boost shutoff, 30FF is underboost I believe. I was getting 30FF for a while and went crazy trying to find the issue. turns out it is my boost solenoids.

Usually 3100 is accompanied by other codes

Well I replaced the hoses as well just in case. They were fine but might as well...

I replaced the ones from the canisters to the solenoids, and the ones from the canisters to the engine vacuum pump. Only ones I didn't are the ones from the boost solenoids to the WG s
