dejon tool mbc 2 stage

[1gengsxz3]

i just got one and hooked it up everything is correct but it's not seeming to control boost why not? did any one ever figure it out yet i mean i was hitting 16 psi on both settings and i even loosened the thumb screw like crazy whats going on? any suggestion would be great.

are you supposed to hook the hose that goes to waste gate actuator to the waste gate or the j pipe i'm sure it's the waste gate but you never know

u might have some lines on wrong

OP, are you sure that the solenoid is actuating to open/close the secondary valve? You might be stuck at 16psi if the wiring is not correct.

The lines should be set up the way any other mbc's are, which is that the input comes from the j-pipe (or other boost source) and the output goes to the wastegate. If you know which way air flows through the controller, then hook it up like I described. Back out both the adjusters, open the solenoid (for high psi driving) and you should be on stock wastegate spring pressure only. From there, set the high and low boost levels.
