ecmlink boost control solenoid

[toppertopper]

Was having my car tuned today , for wot pull was only able to get to 5.5 (not bars) ...Going to be logging wgduty tomorrow , as well as checking to make sure the bcs is turning on ..but it might not be , because of wiring it was a n/t car then converted into a turbo car ..So the wiring may not be right , wanting to run it off the ecu wires so its done right (if its not turning on)...So i need some help there.. I wire one to pin 105 but where do i wire the other wire to ??
Any thing else to check for , did blt's , wg spring is 14.7 , double checked all the hoses and routing diagrams

If the wastegate spring is 14.7, and you are only running 5.5 psi, their is another issues beside the boost controller. For you to be running less than wastegate pressure the gate isn't fully closing, you have a pre turbo exhaust leak, a major exhaust restriction, or a boost leak.

maybe the firing ring is backwards ?? not letting it fully close .. will double check that to.i do believe that is the problem after looking at some pics

the fire ring was on right ,But the bcs is not turning on ..How do i wire it to the ecu ..pin 105 and ??

figured it out pin 105 for power and knock sensor for switched ground ,...hopfully that is the problem

Like donniekak said above the boost control solenoid can only raise boost not lower it, so if your boost is below wastegate pressure you have a boost or exhaust leak somewhere or some other issue.
