Today I recieved my MBC and I hooked it up and when I press on the Gas it is not giving me any power 2500rpm pedal to the medal. Here is a video of my setup.....

I Spliced from my wastegate hose coming off the intake manifold and attached the MBC now its not giving me any power.. I saw some articles on here but it just got me confused on how to set it up.....

I'm going to eat with my wife so I will be on in a little bit...I know someone knows how to do it so thanks in advance...
 
I know right...I'm pretty sure its something simple I'm looking past. I mean I did everything I can to troubleshoot other than the boost leak test but I mean its really happening.. I have the video and its not going anyhigher on the rpm..I will try tommorow to shoot a full video of the whole thing..

Take a video of all your vac/ boost connections... Like at the intake mani, bov where it goes, how you have it hooked up to your intake pipe... But really the only thing that has ever made my car not rev past 2500 is the MAS cable being disconnected... Like the last 2 said, DSM Mystery...
 
Maybe its telling you to get a boost gauge before you worry about turning up the boost.:D:p.

When you put it back to how it was before where are you hooking the vac lines too?
 
Here is an updated Video today I have taken about an hour ago..Its dark now so I can't take anymore videos..MBC INSTALL 3 video by 95gsxguy_2009 - PhotobucketAnyways I started it today and after I turned it off.. I tried to start it again but no start..I am not worried about starting the car right now I just wanna know if all the hoses are hooked up right...Thanks
 
Everything is right on the MBC side.

However, is your FPR still hooked up? I can't tell what that vacuum line coming off the manifold on the drivers side is going to. Should be a boost gauge if you have one and the FPR.
 
I would say you need to check for a leak. Make sure you check your MBC. I had a leak there that toook me forever to find.
 
Ok so today I went to go and install my Boost guage and since yesterday my car wasn't starting.. And I tried today but it is not starting..It turns over but wont even start. IT will bog down pretty quick and then die. Is it because of my MBC? before the install it was running fine, after the install it was still running fine. But after a couple of days of starting it out now It wont start and stay on. What can be wrong?
