Low boost!!!

Low boost!!!
So I have 50hp ddp injector that are new, new denny t stage 2 fuel pin new lift pump and new fuel filter. Now I had full fuel screw in like 2 turns and the idle was really high and would have trouble starting. And when driving down the road it wouldn't go past 25 psi of boost. What would this be?

By no means a guru on these but a couple of more points.
If no smoke when this is happening and the low temps would indeed seem a lack of fuel.
If it is still the stock turbo it will be laggy down low.
How was it running before adding these parts? Did you do all the changes at the same time.
May need to add a pressure gauge to the fuel system to confirm your pressure.

I got the motor all apart . But I put all the upgrades in it at same time and its stock turbo. I got the ffs about 1 1/2 turns in and star wheel all way in and smoke screw all way in. Also have stage 2 Denny t fuel pin. And when at wide open throttle it barely makes 20lbs boost and doesn't smoke at all. And barely smokes at lower rpm

i havent had the chance yet to get my fuel gauge hooked up, but my motor is idling at around 900 rpms and when i turn the idle screw down it doesnt change the idle at all. and when i advance the pump a 1/8'' it gives it no extra power really. now when i drive down the road it feels like im only getting half power and it doesnt smoke or haze at all when at wot. and i was told it may be the brain, but what is the brain?
