why the hell does my car not boost over 10 psi? it is bothering the crap out of me! someone please give me some info!!!!!! PLEASE

 

I think that you are running on the wastegate pressure (~10 psi)
Maybe your FBC isn't working properly?

I heard it might be something about a brass restrictor in the turbo hose.
or..
may be the hoses aren't connected in the right way?

What did you do to your car before that happened?

(I had the same situation when I tried to disconnect the MBC and switch back to FBC)

 

that is exactly what i did!!!!!!!!!! how did you fix that??????????? please help me out.......

 

nothing horrible happened to your engine right???? ////////

 

follow the links in this thread for diagrams and part numbers of how to connect everything, and order anything you don't have.

what exactly did you do though to fix it?

 

So you are trying to go back to FBC from EBC?

you need to connect everything to the right place (basically hoses from the turbo to the FBC) to make your FBC work and let your turbo boost over the waste gate pressure.

 

it's just that the FBC is not connected to the turbo while I disconnect the EBC.
i.e There was no Boost control for the turbo at that time to hold the boost pass 10psi, that's all.

 

i am tryin to go back to FBC from MBC. i hooked up all the hoses right so i dont knwo what else to do..... did you have to do anything electronicaly to resest anything?
