Here's the story so far:

Used to have an S4 Turbo on my S5 TII motor. I have a manual boost controller. No matter how much I turned it up or down, it always boosted to ~5PSI. I then installed an S5 Hybrid turbo, and it still would boost to ~5PSI regardless of what setting the boost controller was at. So I did some searching on here, and someone mentioned that the controllers only work one way. So, I switched the lines around, and voila! Without even giving it lots of gas, it boosted up to ~11 PSI. So i was pumped, but turned it back down, because I didnt want to run that high. Now, I turned it back up again but its doing the same thing as before! It wont go past 5-6 PSI.

So, I figured the boost controller was the issue. So I bypassed it, by just connecting the two lines together, that way it would boost to whatever it wanted. I was very careful with the throttle, just so it wouldnt boost to something stupidly high and wreck something. But, alas, it again went only to 5-6 PSI.

Does anyone know what the problem may be? I would like to run around 10 PSI, maybe higher. The engine was rebuilt about... 6000 KM ago, and the turbo has about 2000 KM on it also.


A side note: My BOV (Apexi Dual Chamber) is so quiet, i can almost never hear it. I was told to adjust it, you loosen the top screw until ____ happens, and then tighten the nut and its good to go. Anyone want to confirm this, or fill in the blanks?

Just to check have you dealt with fuel cut control? it's an elementary, question, but I have to know. and I'm guessing the stock computer..no piggybacks. what else has been done?

Turns out it was just a really crappy boost controller. I picked up a Turbosmart MBC, and she runs like a champ now!
