Is there a slight chance it could be my BOV that is leaking at such high boost and thats why it doesnt hold.

 

If the MBc is closed its supposed to be Stock, IF I open it a littl efrom there will it add to Stock or will it start from like 11psi

 

More baseless warnings about lower boost lol. Your car will run fine with minimal boost, but you do need a boost controller.

 

11 PSI is "stock" when you add an aftermarket boost controler.

 

ok, so if I have it closed all the way, it should say 11psi, and it doesnt, it reacts like stock

 

I have figured it out , the pros that installed my MBC, were still connecting the selenoid to the equation. So im guessing thats why it tapers, because the ECU is still telling to taper at high rpms.
So I have to disconnect the selenoid two, and plug the 2 holes, but what do I plug them with?

and 'T' the BOV line, and thats when my boost will hold to redline.

Taking selenoid out is the way, but is it safer, will more constant boost mess something up?

thanks for all of your replys, even the bad ones..but hey we are here to learn right

Thanks EvoM.

 

You don't have to plug the solenoid, but you can use some vacuum hose end caps that are sold at any auto parts shop (Napa, Auto Zone, Pep Boys, etc.).

Constant boost won't hurt anything, just keep it below 20 PSI. I'd recommend 18 PSI and leave it there until you get more mods that will actually use the higher pressure efficiently.

There really isn't any safety to worry about. The ECU will still be in place to monitor the air flow, and will still initiate fuel cut if it gets too lean.
