Tech Help: Unknown Fault Codes + Solutions Needed
Ok So I'll start wit my car and engine spec and all my work and anyone who has solutions and knowlage of what these codes can feel free to jump in and let me know what to do? The car is running alright but I'm havinga fueling issue. which will be my second question... Do I need to run an adjustable furl pressure regulator with this set up or should my tuning take car of all of that?

Carbon fiber intake (Heat Wrapped)
Forge 007 DV
3" Downpipe (Heat Wrapped) Stock o2 Sensor
3" Exhaust (Heat Wrapped back to Flex Piece)
and here are the FAULT CODES... Some I know and dont know what they are and some I couldnt find?...

17956 Boost pressure control valve open.
17880 EVAP emission control short to ground
17604 Bank 1 oxygen sensor 1heater electrical malfunction
17606 Bank 1 oxygen sensor 2 heater electrical malfunction
17968 Maximum engine speed exceeded ( no sh*t with that tuning)
16985 ECM check sum memory error ( not sure how your tuning affects this, but this is worrisome for a failing Engine control module.

Clear them all and see what comes back.
956 sounds like your N75 valve. This is probably being thrown because you have a different boost controler.
The worrisome one to me is the 985 which indicates a faulty ECM. What fueling problems are you having?
