help with misfire!

My car today would spike up to 21 psi like it normally does, but rather than sitting at 20 psi until redline boost dropped down to 15 / 16 instantly and the car misfired badly. It did this everytime after that as well. I was on the way to work so I didn't have a chance to look at it yet, but I'm assuming just a vacuum line or intercooler pipe is most likely the cause? Part throttle and idle seem fine, only when I'm in boost. There is no blue smoke under boost though, so the turbo seems fine.

This is on my new car - 1997 gst, not the gsx in my profile. I've been out of dsms for a while and just getting back in so it may take a minute for me to remember everything. I just realized there is a problem diagnosis section, if if I mod could move it to the proper section I would appreciate it. Thanks!

I would say boost leak.

It was a torn diaphram on my bov. I put on a new bov and the car runs awesome now, this may be closed. Thanks.

It's still a boostleak, I win congrats on the fix!
