mbc install engine acts up now

[pur97tsifwd]

ok i got a mbc from slowboy racing this is how i installed it i put the vacuum fitting with 2 holes (1 hole bleeder) on the waste gate the other on the j pipe off the turbo i have the boost controller set with the screw all the way out and my bov is hooked up like this the vacuum line goes to my intake manifold

when i went and drove my car i still have the stock boost gauge it hits 14 and around 10 or so the car will shake and stutter and i have the controller turned all the way down

i was told the bov is suppose to be hooked up to the j pipe but i only have 1 nipple

I have seen big shops run turbos without a bov/bpv. That don't make it right. If you want manifold vac on the wastegate just tap and run a fresh line from the manifold.
To the poster it sounds like you have boost leak issues. And it is not to smart to put a boost controller on your car with out a boost gauge that works. That is almost as bad as installing 1000cc injectors on a stock ecu with not tuning device. It's your car so do what you want but you are shooting in the dark blind folded with ear plugs without a boost gauge.
