followed the Tech guide on tuners. plugged the turbo housing, wastegate into MBC out of MBC T'ed into 1g Bov line ( the one fom the top of thebov into the intake manifold) unplugged old BCS and plugged the nipple on radiator side of my intake.... car will just boost untill sputters any solutions, or had this problem

anyone, what am I missing???

Umm on my car the wastegate is off of the turbo only. It goes form the piping(Pressure) to the MBC, then MBC to the Wastegate. My BOV is straight from manifold to BOV. Make sure you have the pressure the right way into the MBC too.

so what does that have to do with your BOV not working

**CornFed2.4** · 03-24-2006

I titled it wrong its really my MBC thats f'ed up the turbo just spools up and @about 17 psi it sputters out MBC is as high as it goes on the nut just making sure I diidnt miis something that was not in the tuners tech article... and with the stock BCS I was running 13 psi just fine

you turn the screw in on the MBC to lower the boost.

Are you sure, I thought it wass the other way around.

You turn the screw out to lower boost (loosen).

I dunno what kind of MBC you guys have but they are a bleed valve, and the farther out you turn the more air can escape before the wastgate. Ever MBC i have seen is out for more boost and in for less. Well good luck anyways

With a typical ball/spring boost controller out (counter clockwise) is for less boost and in (clockwise) is higher boost. Bleeder valves do not make good boost controllers, leave it in your fish tank.

Also, you'd be better off using your turbo-outlet nipple as a preasure source instead of the BOV line, this will help control/eliminate boost spike.

its a ball and spring MBC, and just plug it into the the turbo outlet on the housing rather than the bov line thanks all try again when I hook up my maf translator
