i would try skipping the tee, put the boost source in from the lower port on the big piece, and the upper port to the wastegate.

if you have an air compressor at home you can bench test first.

Hallman makes a nice unit. Worth the little bit of extra money you spend on a MBC over a comparative Ebay unit.

i use a $14 ebay unit without all the other fancy doodads. boost is ROCK STEADY.

dont spend money you dont have to.

I have thrown away quite a few cheap ebay units as well....the Hallman Pro is not that expensive and from my experience has been a very reliable unit in many different builds. As stated above, one side to boost reference, other side directly to the side port on the Tial and leave the top port open to atmosphere.

Ive bought two ebay units. one with the bleed port and the other without. one for 12 bucks the other was $14 shipped. both have worked perfectly.

it aint rocket surgery. they all use a ball and spring, so paying 90 bucks or whatever it is for one is kind of insane.

hallman pro or the Blox manual controller ( hallman copy)

I have one of these. I can't figure out the Tee. I assume it's supposed to be a check valve but usually you can blow throw it from one end and not the other. I can get air to go thru from either end. What's the purpose of the check valve anyway?

The one I have on my corvette its backwards from what it says . When we put it on the dyno and tried to turn the boost up it went down .Don't know why but its backwards.
