Here's the symptoms, I'll be driving to work in my usual spirited manner and after the first 5 or so miles of running/boosting fine, it'll over boost. I'll be steadily climbing in boost and then around 5 psi it'll quickly rise to 10 psi. I've seen it go to 12 psi at times too. I'm not too worried about this since 10 psi is factory spec, but is this really ok to live with for now? All my mods are current on my mod list. I don't remember when exactly this first started, but I know it never happened before last summer when I installed my Apexi exhaust (full 3in turbo back - no cat). Still factory fuel system, no mbc, no boost controller, big T28-internally gated, no porting. Like I said, I'm not overly concerned since it doesn't go past 12 psi (prosport Evo boost gauge), but would still like to find out more to this beyond the posts I just read.
