I've been away from cssnet for a while now but I'm back.
Got another ss, 2.8, 60s, header with 2.5" catless system. Pretty loud, makes 15psi. Boost seems normal but I get a p0033 bypass solenoid code. I swapped out the solenoid and its still throwing that code, quick quickly too.
Vacuum lines are new. Routing correct.
Anyone have advice for me? There is not much info about this around.

 

the code definition is "supercharger bypass valve solenoid control circuit fault". the solenoid circuit is everything from the solenoid itself, to the connector and the wiring itself. the code coming back right after clearing it tells me you have an open circuit.

check the connector for damaged pins, and check your wiring harness for abrasions or cuts.
