After turning up the boost machine, can't boost past 15PSI anymore even without it
So I pulled the boost machine off, and still does the same thing now. I turned off my APR chip, and car holds 10PSI or so fine. If I don't boost much, the car drives with no problems.
I have recent new coilpacks and plugs, TB done, checked DV and it seems ok, hoses seem ok.
