Up pipe leak or weak wastegate actuator

Hey guys, I can get to 22 pounds of boost on both of my highest chip settings and only 12 on stock. When I unplug my actuator I still get to same amount. I made sure none of my boots were leaking. I think it's the actuator getting weak but I want to be sure before I just throw money at it. Thanks in advance.

What chip?
How did you make sure the boots weren't leaking? Best way is to pressurize the intake system while the truck is off.
If the exhaust is leaking preturbo, you should see soot marks around any connections.

I built a boost leak detector like you said and saw my ebp tube mounting bracket was leaking Pretty bad where is presses against the hpop(I guess that's what it is) at about 5 psi. Do you know where I can get a new one or if it's good to try to reveal it? I guess I messed it up when I was cleaning it not too long ago.

So you pressurized the intake and exhaust sides both?

I'd replace it, but not for the fact that it's going to lose so much exhaust as to affect turbo performance, but that it's losing so much exhaust as to not let the PCM see actual EBP reading, thus affecting performance possibly.

i just put air in through the inake side. How would you test the exhaust side? I understand that the tube is connected to the exhaust side but I thought you would have to block off the exhaust pipe.
I'll fix it this weekend probably. Thanks for to help I appreciate it

Well you said the EBP is leaking at about 5PSI
