Please help me find my boost problem.

I have a little problem with my boost. I can only get 7psi in first gear. If I use any other gear I can hit 13psi without any problem. I don't know how to fix this problem or even know what is wrong with my car. Can someone please help me out? As for my mods I have...
Intake
Downpipe
Midpipe
GReddy exhaust
GReddy pulley set
HKS Twin Power
Tie wrap
upgraded fuel pump
Fluidyne Radiator
Blitz boost controller
A'pexi Power FC and Commander

The pill on the wastegate has been changed, because I was experiencing some boost creep. The boost creep is gone, but now I have another problem.

I see you moved forums on me ....

Lets just ask some questions here, if you put the stock pill back in will you get full boost in first gear? Did you change the pill in the precontrol actuator as well?

Strange, in your mod list, you have a boost controller yet you mentioned about a different boost pill. If you have a boost controller it replaces the pill. Who installed the boost controller for you?? If the pill is still there regardless of what it is, the boost controller will not function properly.

Thanks for trying to help me out guys. I had a local shop install the boost controller for me. As for the stock pill I haven't tried putting it back on to see if there is a difference. Actually, I don't have it anymore, I forgot to get it from the shop when my FD was there.

Why wouldn't my boost work properly if the pill is still on? The Power FC controls boost and I never heard of anyone removing the pill when using the Power FC. Also, is there a website that shows exactly where the pill is located?

Thanks

U indicated in your mod list that u have a Blitz boost controller. A stand along boost controller is essentially a wastegate controller. The boost under stock setup uses a 'pill' to limit the wastegate opening to a preset boost level (10 psi for stock). The pill is nothing more then a metal (brass) air restricter (looks a lot like a brass bead) stuffed inside the vacuum hose that goes to the wastegate actuator. The stand along boost controller replaces the pills function (sort of like a variable pill, if u will).
I have not worked with a combo fuel computer/boost controller setup before, but I am almost sure in either case the pill needs to be removed other wise the airflow to the control actuator is limited and the boost level cannot be changed.
