I am showing a max of about 3 PSI. I have fresh supercharger oil that I have not swapped in yet. All systems seem to be good. I am currently getting random P0105 and P1519 codes. I pulled the K40, it is about 4 years old, and the solder looked perfect.
I cleaned around the cam solenoid and wires, and am waiting to see if that was leakage or general filth.
Where do I look for missing boost?
Could be a few things. It's possible that the boost gauge isn't reading properly and the car is fine. On yours, I believe the clutch is set up to engage the SC around 2500 rpm and would give you max boost around 3500 give or take. How does the car perform? Does it seem to make good power? IF it seems weak it could be the ECM or possibly a bad SC clutch. It could also be an issue with the SC bypass valve. Hard to pin it down from here.
