Need some serious help with uncontrollable boost issue...

[ticketmagnet]

Ok this is driving me nuts, i have a forge WGA, turboxs mbc and a blitz bov, i installed them all the same night, i have my wga going to my MBC and my mbc going to the throttle body, i capped off all the other sylanoids(cant spell sorry) this was how i was originally told to do it, when i installed the wga i had it spiking 15 psi with a 13 psi hold, i added the mbc and got 16-17 out of it, it worked perfect for a couple weeks, then all of the sudden it starded idling really funny and no matter how i ajust the wga or the mbc it doesnt effect anything except how fast it raises but it still spieks way to high, past the 20psi mark...ive tried everything from rechecking all my lines to resetting the ecu. Im fixing to put everything back to stock and try it all again, if anyone knows what is causing it to do this i could use every bit of imformation to fix this problem faster. Is there some vacuum lines the MUST stay hooked up no matter what?

This is ur first problem... its hooked up wrong.
1st hook from WGA to MBC to turbo nipple on back of turbo.
2nd i only have the red line and white line in
Look at this pic.
This is how i have mine hooked. It works great.
If u have questions. refer to pic.

I tried the Psi-Fi setup too, but now I'm using DRIZZE99's method.....neither work for me as it does the same as your car TICKETMAGNET Spools to 22psi fast, hesitates,drops to 15 no matter what. I'm fighting this too. Does anyone think it could be the spring in the mbc?

[ticketmagnet]

I dont think so, i just unhooked the mbc completly and have just the wga hooked up and its still doing it....im thinking maybe a leak someplace....im gonna see if i can figure it out since i wasnt able to get my car running properly for the races tonight, so if i come up with anything ill post it for ya to try out.

i don't think you can get rid of the idle problem but the boost you can cure.
