Stock Boost?

Q&A regarding engines, turbos, and intercoolers and power upgrades

If your vacuum reading is stable, I don't think you have any leak.
It sounds like your MBC or wastegate problem, not the vacuum leak.

Did you have these problems before you got the mbc? Even if your wg actuator is shot, it won't see any boost 'till the mbc opens.....

I haven't been keeping up with this thread much, but does your MBC have a bleeder valve? I've heard from somewhere that unless you're boosting a pretty good amount of boost, the bleeder valve will cause spiking.

To me, it looks like your MBC is messing everything up. Make your own WITHOUT a bleeder valve (basically, don't drill that stupid hole ;))

Yup, i traced it back to my Boost controller. Im in the process of snatching up an electronic one.

Thanks for the advice guys...

BTW, my wastegate has been modified to take 7psi at stock boost. Which is fair enough, since it used to run in a JDM, and then came here with all the controller pulled. No sweat though.
