Ok, so I'm tuning on SD and my tuner says the 3 port isn't working correctly. Will only go to 19-20 psi and hold it strong. I replaced the HOA Import 3 port with an RRE 3 port. Same thing.

So my question is... is there a fuse or something that goes to the 3 port? It's hooked up to the stock solenoid connector. So perhaps it's not getting power? Need some ideas. Thanks.

 

Post up your wgdc tables.
Also if it were not working, I assume it would run wastegate pressure, what actuator do you have? Lastly if you run the vac line from the boost source directly to the actuator does it hit the same boost level?

 

having the same issue, end up using the MBC.

 

I had the same problem... I am running motec m800 ecu. Solved the problem with MBC...can t believe it.

I have the MAC 3 port...

 

I am being tuned now and running hybrid boost on SD. I have a Grimmspeed 3 port. Its hooked up correctly and has 12.4v at the plug. It does nothing? I'm running on just the manual control.
