TURBO FINALLY IN!.. but small problem...

[s13silady]

ok my turbo is finally in....after 3 days of constant rootbeers and other good stuff, its in...
i finally started up the car today... it idled really good... but it idled pretty high... i still have to retard my timing...(is that the way to lower idle?)

ok my problem is that after the car gets started, it idles good.. but give or take a couple of minutes after that, it starts to idle horribly... and eventually die...i took it around the block to see what happens, and it stalls when i come to stop.. not all the time, but half the time i stop...

im pretty sure i have everything hooked up right..i dont know what the problem is, im thinking because i did not run a fitting to my hotpipe for the wastegate, and instead T'ed off vaccum..but someone told me that i could do it.. maybe its not the right vaccum.... what could other possible problems be???
also my car spits out really ****e smoke from exhaust... and everyonce in a while from the bottom of my car (engine area)...
i have a huge power loss and what seems wierd is i hooked up my boost guage (temporarily) just to see if its reading any boost, and it sez 0 psi... maybe i hooked stuff up wrong...
can anyone help me by telling me what needs to get hooked up where and what doesnt need to be hooked up...
if you guys can respond with previous post that were already made (i tried searching by the way) or try to explain to me please

Edit: oh yah my setup (if you need to know) is as follows:

KKK's turbo
Vortech FMU
JGS Manifold
Spearco FMIC
Apexi twin chamber BOV
Tial 35mm .3 bar wastegate
custom IC piping
this is all on stock internals..
and i have no MBC so im stuck at 4.35(or about there) psi..
