So in the past I was able to boost to what I set the boost controller to...1 bar. Over the years my boost would fluctuate from .7 to 1 bar and the engine would accelerate in pulsations. Now, my boost won't usually be able to even boost steadily at .5ish bar, it'll bounce around from .3 to .6 bar. This makes me think that my boost controller is stuck open or something and it basically is relying on the wastegate pressure of 7psi. Just recently if I do a boost leak test, the 4th port (drainage port) on the boost controller will start leaking all of the air out on a 5 psi test. Does it make sense to say my boost controller is toast?
