Default Boost, EGT and smoke issues....

Hello everyone. I need some of your collective knowledge to help with my problems. Here is where I am sitting engine-wise:

Rebuilt motor bored to largest oversized pistons
12mm pump
Turbonetics Super 60 T3 with .82 ar
Turbonetics WG
Turbonetics manual boost controller
Air/water intercooler
Boost gauge
EGT
ARP Head Studs
3" DP

Now to the problems:

-Not building more than 10 lbs of boost...why?

-Black clouds of smoke (I think I about have this figured out)

-IP timing set to .96. Make minor adjustments with the inboard/outboard rotation. Outboard (to driver side) brings the EGT's down and runs better. Inboard raises EGT's and runs worse.

-Boost builds, then falls off at the high side of the rpm's. I initially thought it was due to excessive back pressure so I went up to a 3" down pipe. It helped with the smoke issue and seemed to help overall, but something is causing the boost to fall off and not reach over 10 lbs. My target boost is 20 lbs...just can't get there for some reason.

Any suggestions?

Thanks,
Phil
