How have you plumbed the controller?

Are you using the stock ECU? If so, did you bypass the stock boost solenoid?

the controller has pluming. i am using the stock ecu, is the stock boost solenoid the pressure sensor if so i removed the line and blocked it off but that didnt help

Everything looks correct in your video but I'm not really familiar with this specific boost controller. Does it have a setting for the type of wastegate used? Make sure that it is set to a swing valve/flapper and not a poppet type.

How many ports does the solenoid have?

the solenoid has 3 ports one in one out and one bleeder.

the thing is i had it working in my 240 with no problems
