My MBC is not working or something is restricting it for some reason. I have all the supporting mods for it to run 15psi like its nothing but it won't go up at all. I installed it right because the first day I had it I adjusted itto get my boost to peak at 15 psi then I drive my car the next day and it won't peak a hair over 12psi. Between days i removed my bumper cover in preperation to install my FMIC but long story short it never came in the mail. So I put it back onand didnt change anything. I am running a 255 pump and 550 injectors with the stockside mountintercooler. other mods are in my sig. Any1 know what the problem could be?

 

did you tee your mbc into the line or no?

 

No I have one end running to the turbo and the other to the waste gate. Should i instead of running the line to the tubo should i run it to the line coming off of the BOV?

 

well i have mine on my gst setup like you do i dont know what would really cause maybe a bad mbc i dont know man.I really hope some of the pros come give us their advice. they seem to bemuch more help than i am

 

any ideas?

 

just upin the thread. I really could use some help please. My warranty is about to go up on my MBC andneed to know if it was me doing something wrong or its broke.

 

Do a boost leak check Pribs.

I'll def do a test tommorow but its strange I had my mbc set at 15 psi then it just seems likethe mbc isnot even there. I turn it all the way down or all the way up and stil at 12 psi. I couldsee it not going up because of a leak but wouldn't itatleast go down when I turnthe boost down?

 

Yeah, it should. What kind of MBC is this again?
What kind of bov do you have again?
