hey guys just had a few quick questions...
right now i am just running off the wastegate of my rx6 turbo kit to control my boost. the wastegate has already been modified so it won't stick.
anyway i went to install my new blitz boost controller and i can't figure some things out.
first my boost controller is not registering any boost.
second my car actually overboosted and i don't know why since it seems that the boost controller isn't seeeing any boost.
my waste gate has two nipples on it. the nipple coming from the side of the wastegate is going to a tap on the manifold. the nipple on the top of the wastegate is going to the "out" nipple on the boost controller solenoid, and the in nipple hose is coming from a tap right after the turbo.
before i installed it i had the nipple on top of the wastegate plugged up and the nipple on the side of the wastegate going to the nipple right after the turbo, it was a consistant 13 lbs all day long just running off the wastegate.
anyway if you have any ideas why i would be overboosting as well as why my EBC doesn't seem to be registering any boost let me know cause i am quite complexed... i figured if it was registering any boost it shouldn't be over boosting... but i have no idea now... thanks,
john
ps from what i can tell the boost controller is set at holding boost at .6 bar much less than the wastegate, and the warning is @ 1 bar,

The nipple on the side of the wastegate should still go to the connection right after the turbo like it used to. 'T' that line so it can go to the boost controller and the side of the wastegate. Pneumatically 
you should be right on then, this is not that big a deal.
Your wiring problems are another matter, as I don't know your boost controller. It would seem that if the boost controller doesn't see any boost it will continue to try to raise the boost until it does, hence the overboosting.
