there is, but you need a way to closely monitor your boost.
you would take the hose off of your wastegate actuator (coming from your actuator) and go for a drive while watching your boost like a hawk, stay out of boost. find a place where you can get into boost, while still watching your boost like a hawk, see if you can make more than 8lbs, dont go past 12-13lbs. If you can make more than 8lbs, its your actuator. a stock actuator is plug and play, an aftermarket unit like grimmspeed's requires a custom tune. you decide.
Good luck and please do not do this without a way to monitor your boost.

Not necessarily, he could have a low DAM and the ECU has disabled boost control to protect the engine.

Wouldn't this result in a check engine light? Knock correction/learning etc. even if there was a bad knock sensor, it would throw a cel and put you into limp mode (making about 8 lbs of boost and smelling like gasoline) O.p. do you have any check engine lights?

No, low DAM doesn't throw any CELs or put the car in limp mode, it just disables boost control.

CELs are generally reserved for problems that affect emissions, lack of a CEL doesn't mean the car is running correctly, it doesn't even mean that the car thinks it's running correctly.

Stick with the stock ebcs for now, u can get a working used one really cheap. Get the car smoke tested, I had lots of dry rotted vaccum lines and some fuel return issues when my car had the same problem with boost

check your Bpv make sure that its not sticking in any way, check for rotted vac lines..
check for that bleeder nipple the guys posted previously ..

check your up pipe make sure it does not have a crack or hole, check inter cooler piping review anything that has been recently replaced within the last few thousand miles.

very hard to troubleshoot my friend via internet :-s could be a bad injector rubber o ring allowing air into the intake manifold..

Personally I would use the tactrix cable to pull a Learningview and check your DAM and your fuel trims and then proceed from there. Like Eggroll said a reduced DAM will disable boost. That would be the first thing that I would do BEFORE buying anything else.

to check the solenoid, you will need a way to blow through it and a way to actuate it electrically.

no power = air is blocked
power applied through coil = should feel a click, and air passes through

the coil is not polarized, meaning you can connect either side to + to actuate. the solenoid runs off battery voltage (not 5v).

I have a cobb accessport so i will be able to watch my boost and i can data log any information that would help find the source.

Isn't the cobb ots map for stage 2 at 16lbs of boost? anyway like stated before, My knowledge of tuning and dam is limited, but after a little research, its seems that a dam of 16 is normal for your setup. take this for what its worth, but I'm still pointing at your solenoid.

16 is normal for DAM on the 16-bit ECUs (02-05 WRX), so it's not the ECU cutting boost due to knock. As long as your WGDC logs normal, then the solenoid looks like a good place to check next.

do you have any close friends with wrx's? you could see if anyone close has a suitable solenoid and willing to come over and let you swap it out to see if it fixes your problem.
Make sure all of the contacts in the solenoid plug are clean as well.

take 2 pieces of wire. attach one end of one piece to battery +, one end of the other piece to battery -. Then put the two loose ends across the coil connections of your solenoid. You should hear and feel it click. additionally you should be able to blow through it while actuated.
