I keep getting the p1104 engine code. It doesn't say a description but from what i've read its the BCS, I went ahead and replaced that it, reset the ECU it comes back after I start the car up the 2nd time. What the heck could be the issue, just to make sure I have the hoses connected right, the top port goes to the intake, bottom hose goes to a T and then to the wastegate and J pipe
 
This fault code is generally thrown if the electrical connector is not plugged-in at the bottom of the BCS. Make sure that the electrical connector is plugged-in properly to the BCS. Hope this helps you.:thumb:
 
Yes it's plugged in, I swapped out 2 of them with the same results. I cleaned the connectors and everything

well it has to be the wiring, I put in one from a friend who's works and I still get the cel. I'll try and disable it with the ceddymod flash
