After fixing vacuum leaks, lower boost?
I knew my primaries injectors needed changing because of excessive backfiring and fuel burning below 4000 rpm's. I got in there to find very new injectors, but installed crappy. No plastic spacer, no rubber grommets, things like that. I put in new injectors and fixed a bunch of leaks and such. Now I get less boost. Could the leaks have caused higher boost and now it just doesn't boost as high? I hope this is the case. Would putting 550cc injectors in the primaries be the problem? I don't think they were since I put them with other TII injectors in my shop, but they could have gotten mixed up with some NA ones. Please help.

Must...scrub...parts...
If you had a vac leak in one of the lines to/from the waste gate actuator valve that would prevent the wastegate from opening, or require more boost to open it, increasing boost.
