Under Boosting
Been having problems with my car where I will only boost to 7.7 psi max. I’ve since changed out all my vacuum lines, boost solenoid and retightened all my couplers. Before doing all of that the car would only go to 2-5 psi. The only codes thrown are 2D15, 2CED and 321D.

As of today I took out the water pump to get to my diverter valve. Saw that the brass piston was having a hard time moving. Added oil to it to make it move smooth again. Car was definitely smoother but still only around 7 psi |
