maybe you have an aftermarket wga and dont know it or maybe your stock one is preloaded too much. i believe the fp wga looks stock but i could be wrong. if you did that test and it still ran the same psi it sounds to me like that is just what the wga is set to

 

All the T's are not necessary to test the WG.

Just connect the WG nipple to the turbo nipple. That will tell you exactly what your WG pressure is.

I don't know how much you are turning the boost controller, but start it at the lowest setting and gradually increase until you see an increase over WG pressure. If you're at the point where it's maxed out and boost still goes up, then you know for sure it's a problem.

It is a possibility that there wasn't enough preload on the MBC to make a change over 22 psi, if in fact you have a 22 psi WG.

 

Also you can test in 3rd.

 

I connected the WG nipple to the turbo nipple, and drove and its still at 22psi. I had to take the MBC off to do this tho. Even when i put the MBC back on i have it turned down all the way, and boost does not change. If i turn the MBC up boost still doesnt change, stays at 22psi.

 

First of all, he has to establish what the waste gate spring pressure is. Normally base pressure is about 11-12 PSI with a stock actuator. Since he is seeing 22 PSI, then we need him to determine whether the WGA is preloaded up to that level.

Now that you have the WGA connected directly to the compressor discharge nipple. Loosen the backup nut that fixes the position of the turnbuckle on the tip of the actuator rod. Remove the cotter pin. Pry the turnbuckle away from its home on the flapper valve's pivot arm peg. Rotate the turnbuckle counterclockwise(outward) until it gets to the point where the hole located on the turnbuckle's flat tip freely slides on and off of its home on the flapper valve's pivot arm peg. reinstall the cotter pin.Take the car for a spin and report back what boost level you see. It should be somewhere between 11-14 PSI.

To do this correctly you either need to have the MBC disconnected and the nipple on the WGA connected directly to the nipple on the comp discharge tube, or, alternately if you leave the MBC connected then just turn it out all the way out counterclockwise to full soft.

 

Maybe the map your boy loaded runs ECU boost??

 

He's currently running a MBC, I think. If so, then ECU & BCS would be out of the loop, AFAIK.

 

Yea but it isnt doing a damn thing for him which is why Im guessing a long shot that the map that was loaded by a friend may be set up for ECU boost...

 

I agree with you.

 

Okay well you wanted me to turn the whole rod of the WG right? Not just the tip of the rod? Well i turned the whole rod counter clockwise once, and still boost the same. This is with the MBC still on but turned all the way down. I ordered another WGA from one of the evom members, it should be here in a few days. Should i just throw that one on and see if that fixes it?

 

Sorry I wasn't specific enough in my instructions. You are not supposed to turn the actuator rod as a whole. You only rotate the turnbuckle (tip) on the threaded end of the rod. I assumed that you knew this. I apologize if you damaged the WGA.

To rotate the turnbuckle: 1) loosen backup nut located behind the turnbuckle along the threaded end of the actuator rod. Remove the cotter pin that secures the turnbuckle end of the rod onto the peg on the flapper valve's pivot arm on the turbine housing. 3) Pry the turnbuckle/actuator rod assembly away from the pivot arm peg by using a large flat-blade screwdriver. Now you can rotate the turnbuckle along the length of the threaded end of the actuator rod with your fingers.

 

Okay sounds good im going to give that a try this weekend. Not a big deal because i ordered another WGA just in case for decently cheap. You only wanted me to turn it counter clockwise just one time?

 

I just reread this, thanks for all the help.(Rotate the turnbuckle counterclockwise(outward) until it gets to the point where the hole located on the turnbuckle's flat tip freely slides on and off of its home on the flapper valve's pivot arm peg.)

 

Can you post a picture or explain exactly how you have your MBC hooked up. Have you tried switching the hoses on your MBC. Not trying to insult your intelligence but that would explain everything and be a simple mistake.

My only caveat to that is normally when that happens, you create alot of boost.

Anyway, pics, diagram or explanation would help.

 

Okay i dont have picture right now, but i set it up exactly like this diagram. I know for sure that i set the MBC up correctly. Im pretty sure that the WGA was messed with by previous owner, so im going to adjust it this weekend.
