Boost pressures
Ive got the stage 5's in and I can't seem to get more than 30#s of boost and that is what I was getting with the stock injectors.The juice w/att. came with the elbow on the turbo and I thought that was to allow more boost. What do I do to fix it?

You may have a leak somewhere. I have the Juice and stock injectors and can get 32psi on level 1. I turnbuckled my wastegate also. I have to really step on it to see that amount of boost though, or hauling somthing real heavy.

You should see more than 30 lbs from stage 5's. See if you can adjust your boost elbow- its probably set at 30. You want it below 35 so I'd leave it be unless your temps are out of control.
It could also be a setting in the juice with egt backdown or something

Turnbuckle is for guys with 2001 and newer autos that came with an HY-35 turbo. You have an HX-35 which is far superior and does not need a turnbuckle but rather a boost elbow, or disconnect the 1/4" silicone line, or a pair of vice grips clamped on the silicone line to prevent air flow to the diaphram that opens the waistgate when sufficient force is applied via boost pressure to overcome the spring tension that holds the gate closed.
FYI don't take boost numbers from anyone with a newer auto as they have a smaller weaker turbo that does not efficiently boost useable air past 28 psi.
Like previously stated, your HX 35 is good for about 35 psi of useable boost air, after that it superheats the air so much to build greater pressure that it gives no further benefit and endagers turbo longevity due to super high rotational speeds. Like 300,000 rpm+.
I personally have a similair setup to you and I cannot get it to make nor want more than 34psi, which is the same max boost that I had with wimpy RV injectors. I can overspeed my turbo but it will not physically make more than 34 psi. I am at high elevation 5000', my turbo is old 220K miles so leaky worn seals, and I could have a small boost leak or two. Last week I found a major boost leak and had to replace the large intake manifold gasket as it was blown out and I could hear it hissing. Definately check the boost elbow and ensure that it is restricting pressure flow to the wastegate actuator. Then I'd buy a 4" plug and fill up the entire system with pressurized air to check for leaks.
