it's possible that the mbc is defected. it happened to me one with a hallman mbc with similar effect after a few high-boost runs at the drag. I replaced it with another mbc and fixed the problem.

 

i found some1 with a spare mbc im going to try it tonight and see how it goes!

 

I have the Perrin inlice MBC, which looks Identical to the Buschar one in your pic. I have had zero problems with it. Today my boost dropped off and wouldn't spike past 12 or 13psi, I tried turning up the boost, still wouldn't move. After that I started checking my lines for a leak and sure enough I found that the rubber fitting I used to connected my boost guage had a small split in it. I replaced the fitting and boost was back to normal.

 

is it normal to instal mbc and open boost without reflash for the time being?

 

People install all kinds of mods without a re-tune. If you aren't going to tune yourself, it's best to do all the mods that you want to do together and then get tuned for them... kind of break up your mods into stages so you don't have to pay for multiple re-tunes

 

well i installed a turboxs mbc last night and amazingly now i can boost just fine. So apparantly my buschur mbc is no good. well hopefully they will replace it. Thanks for all the help guys!

 

Let me know what they say cause I was about to order one...

 

hey! you own me a beer. JK! Great to hear your boost issue resolve. Enjoy.

 

Thank you every1 for the help. Im sending my mbc to buschur today for them to check it out. thanks again

 

Let us know what they have to say cause I'd like to order one...thanks.
