boost won't increase.

Ok. here is the problem wanted to turn up the boost on my car it tops out at 12 PSI but the boost controller is all the way open am I doing this wrong should I be closing it.On one side it has a plus sign and tells you what way to turn. On the other it has a minus sign and tells you what way to turn. I turned in the direction of the plus sign and am still only hitting 12 PSI the turbo is a t-61 and I know it should be hitting more than 12 PSI any thoughts or suggestions are appreciated is it just that the car needs to be tuned.I know that it has never been tuned and it is running off the factory ECU should I upgrade that as well.Thanks!!

Where did you install your mbc at? IIRC, it should be in the vacuum line leading to the wastegate actuator

I am not sure were it is I bought the car with the mods on it already to tell you the truth I dont know much about cars with turbo's in general I bought it because it is one of my dream cars.

Well, take a picture of the boost controller and post it on here. That way we can see what vacuum line it's attached to and see if that's the problem
