Okay so some things have been going on with my car and I can't quite figure it out

A little run down of the the engine
Red top s13 Sr20det in a s14 kouki
T28 apexi b70 turbo
3Inch exhaust
Fmic
63 ecu untuned
Stock 370 injectors
255 walbaro fuel pump
Z32 fuel filter

Now for the problems im having..

In the morning when I cold start my car I notice some smoke on start up but once i give it some gas to go it wants to fall on it's face unless I ease on the gas. Once I get going down the road (car still below full operating temp) and nail it it runs awesome just like it did the first 4 months I had it in the car. Boost on up to 11 to 12 psi like orginally BUT once fully warmed up its only boosting like 6 psi and feels like the power is gone feels like 60% power but it doesn't fall on its face from a stop like it does when it's cold. Don't know if the cold start and the loss in Boost when hot are related and I have a wierd feeling like these are signs of turbo going ??
