Boost Help Please

So I installed my wicked wheel a few weeks ago and never put the actuator back on, finally got a chance to today. I stuck the line going into the wastegate on one of the intercooler tube studs to block it off, hoping to build more pressure like a bunch of other people have. I still only hit 24 pounds though Anyone know what might be going on? any help would be great.

Considering that a "wicked wheel" will move less air, all else constant, expecting more boost is a bit absurd. The whole premise behind it is keeping the compressor out of surge. You have to decrease the pressure at any given flow point to do that.

As far as "what might be going on", to me it looks like you're operating that charger as you should, considering ~25psi is the somewhat advertised limit for those journal bearings.

I didnt install the wheel expecting more air I was just saying I took the actuator off when I put the new wheel on. I plugged the line off expecting to build more boost

If you can remove/re-install the signal line to the actuator (you're not actually removing the actuator fwiw) and the boost remains unchanged, then you don't have enough spring pre-load to hold the gate closed even without any signal to the actuator.

Tighten the actuator rod. At the potential peril of your stock charger...
