Weird...MBC / Guage Help please?

[RockSolidGST]

Ok So i had my guage installed , it was reading around 14-15lbs on stock everything with no controler , Seemed a little high , Got intake , exhaust , downpipe , was reading it was spiking to 18lbs ( still no MBC hooked up ) , Install the MBC Set it , Its reading , and staying at 15lbs.... So the other day i turn the boost up because it almost felt faster without it when it was spiking to 18lbs ( even though i know t25 cuts out at 16lbs )

And i seem to "feel" more power ( no dyno access unfortunatly ) But the gauge is still reading 15lbs , I dont understand , its a tuboXS mbc .... Could the MBC be bad? I know its hooked up right i checked and rechecked it on the vfaq , also had somebody else check it....



Also at 1/2 throttle sometimes there is a little sqeek? strange..


Anything thoughts?

First don't turn up past 16 psi, on stock fuel system and your t25. Trust me you will regret it

On topic though, where do you have your mbc lines hooked up?? Thru the bov line, compressor housing, somewhere else??

My mbc is hooked up threw the bov line , ( i did exactly what vfaq tells you to do ) and the waistgate

I also have walboro 255 , fpr , and a frontmount , so if i wanted , i think i could squueze 1 or 2 psi out of this crap turbo untill i get my new one ( its more for the new one that im worryed about this for )

MBC's should be hooked up to the intake manifold or off the j-pipe/compressor housing. THey should not be tee-d into the bov line it can screw up how your bov is supposed to work, it could open premature and leak your precious boost because the mbc is a bleeder valve.

Keep the boost at 15psi.

Also, aren't the turboXS MBC's bleeder valves???
